Why Get Certified in Java 11, aren't there newer versions available?

Java 11 is designated as the LTS or Long Term Support version of Java - it's going to be supported by Oracle and JDK vendors until at least 2026, unlike Java 9, Java 10, 12, 13, 14, 15, etc all of which are no longer supported by Oracle.

Large companies have large codebases, and it takes them a long time to upgrade that code to new versions of Java - for years Java 8 was the main version used by companies, and with the release of Java 11, and Oracle's commitment to supporting it for many years as well as them designating it as the long term support version, this means that the majority of the industry will be moving, or already have moved to Java 11. Particularly now that Java 8 support is ending soon.

Oracle does not have a certification program for Java 9, 10, 12, or Java 13, etc. This is by design. Because Java 11 is Oracle's long term supported version of Java. For this reason, Java 11 is the version of Java you need to become certified in. And this course will help you achieve that.

Do I really need to take a "Java exam course" to pass the exam?

Being completely upfront, it is possible to pass the exam without studying a specific exam course like this one. But it's not easy. Keep in mind that the exam does not just test your knowledge of Java, but actively tries to trip you up by asking questions that sometimes use obscure, rarely used syntax that you may never have come across before. The sorts of things that most Java courses or textbooks will never teach you.

This course shows you all the standard Java stuff you need to know, as well as this more obscure stuff to ensure you really are ready to pass the exam.

Well Structured & Simple To Memorize: Course has been uncommonly designed to create it simple for the understudies to memorize Java in a basic manner. 24 X 7 Back: I will continuously be there to direct you in your travel to ended up Python master.

Here Is Everything You Will Learn In This Complete Course:

In this hands-on course, you may learn Java right beginning from scratch to the level where you'll be able type in complex Java programs utilizing concepts like OOP, Legacy, Interfacing, Generics etc.

This course will educate you Java right from scratch from a really fundamental level and will slowly move you towards more advanced topics.

In addition to the concepts instructed, this course too has uncommonly designed Practice Cases which is able challenge you and make you think and test what you've got learned.

Section 1: Installing required tools.

In this section we will learn how to download and install the required tools and setup the development environment to start programming in Java.

Section 2: Data types, Arrays & Accepting user input.

In this area we'll learn almost the distinctive types of data sorts in Java. We are going learn almost primitive and non-primitive information sorts in Java additionally how they are distinctive from each other. In primitive information sorts we are going learn almost int, char, drift & boolean. In case of the non-primitive information sorts, we'll cover Clusters. In expansion to data types, we'll moreover learn almost the "Scanner" course which permits us to acknowledge information from the client through the input support. We moreover learn how to form an awfully curiously program for calculating interest. 

Section 3: Conditional & Loops.

In this area we are going broadly cover two major topics i.e conditionals & circles. We are going begin off with an presentation to the "in case" conditional explanation and will learn how program stream can be changed utilizing the conditional explanation. Some time recently composing the code for the conditional "on the off chance that" we to begin with in profundity almost how precisely the conditional explanations work internally.

We at that point take a coding example to get it the in case explanation conjointly learn approximately how we are able settle together different "in case" statements. We at that point learn around the switch case which is additionally a conditional which can be utilized to modify the stream of execution of a program. After which we move ahead to memorize almost consistent administrators which play a major part in conditionals and in choosing the stream of execution of a program. We cover coherent "AND" & "OR" administrators in Java and utilize them with conditionals.

Another we learn around circles, the for and the whereas circle which permit us to emphasize or rehash a set of code different number of times. We too learn how to utilize these circles to repeat through an cluster to get to person cluster components. We too learn almost a extraordinary for circle called as the upgraded for circle which can moreover be utilized to emphasize an array.

Now that we know how to utilize circles to emphasize clusters, we presently jump more profound into multi-dimensional cluster. We too compose a Java program to discover odd & indeed numbers from a given cluster, we perform this errand employing a combination of conditionals, clusters & loops.

To encourage fortify the concepts we learned, we too have a set of challenging hone cases at the conclusion of this area.

Section 4: Object Oriented Programming.

OOP is the heart and code of Java and thus in this area we spend a incredible bargain of time to get it and learn Protest Situated Programming in Java. We begin off by learning what precisely does OOP cruel and how the OOP strategy works. We at that point learn almost how to form objects and classes in Java and see how objects are made internally.

We at that point learn around lesson strategies and learn their noteworthiness in OOP. We type in distinctive methods, make strategies return values conjointly learn how to form lesson strategies that acknowledge parameters. After which we learn approximately constructors which offer assistance us to initialise classes in Java conjointly learn how to form parametrised constructors. We at that point move on to memorize the "this" watchword in Java and it's noteworthiness,

we take an case to memorize how "this" watchword can be utilized to get to occasion factors and lesson strategies. We at that point learn approximately strategy over-burdening and constructor over-burdening and take an case to over-burden lesson strategies in Java.

We at that point learn approximately get to modifiers in Java and utilize them in conjunction with lesson properties and strategies. We learn around get to modifiers such as open, private & secured and learn in profundity approximately how they permit certain portion of the code to be shared and to be kept hidden.

Up following, we learn around legacy which is another most imperative highlights of Java. We learn how to form a course acquire properties and strategies of other classes utilizing the amplifies watchword. We fair do not cover the customary legacy but too cover Various leveled and Multi-level legacy as well.

Marching ahead we learn almost strategy superseding and learn how to abrogate strategies frame the parent lesson in Java. We too learn how to prevent strategy abrogating utilizing the "ultimate" watchword.

Section 5: Exception handling.

In this area we learn, what are special cases? How exemptions can be tossed, caught & dealt with. We learn how to utilize attempt pieces to encase the special case inclined code such that ready to handle an special case when it happens. We are going too learn how to settle different attempt squares interior each other to catch different exemptions in a given program. Apart from this we moreover learn how to form our exceptionally claim custom exemptions additionally how to toss them when needed.

This area is additionally supported by a strong set of hone case, one to handle invalid client ID and other one to handle negative bank stores.

Section 6: Java I/O

This segment bargains with the fundamental I/O operations in Java i.e perusing input from client, showing yield to the client, perusing from records, composing to files etc. In this section we'll cover some of classes from the Java I/O bundle conjointly their strategies which permit us to perform I/O operations. We begin off by learning how Java I/O works and after that learn almost the BufferedReader lesson which is utilized to acknowledge client input and the PrintWriter lesson utilized to show the yield to the client. We'll too learn how to studied and compose information to the records using the related classes. At the conclusion, we compose a program which can store information into a record so that indeed in case the program execution closes, the information would still be protected within the record.

Section 7: Strings

This area is all approximately string course and its strategies. String is one of the foremost broadly utilized information structure in Java and subsequently we learn and get it different string strategies. A few of the string strategy which is able be secured in this area are length, charAt, getChar, toCharArray, rises to, regionMatches, substring, concat, toUpperCase, toLowerCase.

In expansion to this we also learn approximately the StringBuffer lesson as well which has the precise same strategies as the string course but is immutable.

This segment too incorporates a challenging set of hone cases like a secret word length validator, recurrence counter, secret word checker & a discover and supplant program.

 Section 8: Packages & Interfaces.

We'll learn approximately what are Bundles in Java, why they are required and how to form and utilize them. We'll too learn how get to modifiers can be utilized with bundles to avoid get to to certain classes and its strategies. We also learn almost interfacing, how they are created and why they are required.

As a practice example we are going construct a smaller than expected managing an account program that produces utilize of interfacing to force keeping money rules.

Section 9: Java collections.

We learn what are Java collections, what is an ArrayList, how to execute an ArrayList conjointly learn numerous ArrayList strategies which permit us to include things or objects to the ArrayList and manipulate them. We'll too learn almost LinkedList and learn how to form a LinkedList and utilize LinkedList strategies to control things interior a LinkedList. In a similar way we moreover learn around List interface, HashSet, LinkedHashSet & TreeSet at the side their particular strategies. 

 

Section 10: Lambda Expressions.

 In this area we cover lambda expressions and its utilization, we are going learn how to write a lambda expression in Java in conjunction with a utilitarian interface. We'll too learn how to encase a chunk of code into lambdas utilizing piece lambdas. We are going moreover learn approximately utilizing non specific utilitarian interface and how to pass contentions to a lambda expression.

 

Section 11: Generics.

This segment covers generics in java, we'll to begin with begin off with an presentation to generics and after that will really execute generics employing a coding case. We are going learn how to include numerous parameters to a bland, the diverse nonexclusive strategies and bounded sort generics.

 

Section 12: Multithreading.

Multithreading is another vital concept within the Java programming dialect. In this area we study multithreading in detail. We are going learn what could be a string, what may be a life cycle and diverse stages of a string. We'll learn how to reference and get to the most thread in a Java program and how to control it. We'll also learn almost distinctive ways to make a string in Java i.e utilizing the runnable interface and employing a string lesson. We are going too make different strings and watch how they carry on and execute in a multithreaded environment.

To conclude we'll moreover learn around some string strategies such as the connect and the surrender strategy which can be performed on a string.
