As of my last knowledge update in September 2021, I can provide you with a general overview of the basic concepts of Java programming. However, please note that the specifics might vary, and I recommend checking with h2kinfosys or their official resources for the most up-to-date information. Here are some fundamental Java concepts that are commonly covered in introductory Java courses
Java Introduction:

Overview of Java, its history, and its role in software development.
Understanding the Java Virtual Machine (JVM) and its importance in platform independence.

Declaring and using variables.
Primitive data types (int, double, char, boolean, etc.) and their usage.
Operators:

Arithmetic, assignment, comparison, and logical operators.
Increment and decrement operators.
Control Flow:

Conditional statements: if, else if, else.
Switch statements for multiple conditional branches.
Looping constructs: for, while, do-while loops.
Arrays:

Declaring, initializing, and accessing arrays.
Multidimensional arrays.
Methods (Functions):

Defining and calling methods.
Method parameters and return values.
Method overloading.
Object-Oriented Programming (OOP):

Classes and objects.
Constructors and initialization.
Encapsulation, getters, and setters.
Inheritance and subclasses.
Polymorphism and method overriding.
Strings:

String manipulation using built-in methods.
Concatenation and string interpolation.
Exception Handling:

Handling exceptions using try-catch blocks.
Throwing and creating custom exceptions.
Packages and Import Statements:

Organizing code into packages.
Importing classes from other packages.

These are just some of the foundational concepts you might encounter in a basic Java course. As you progress, you'll delve deeper into more advanced topics like generics, interfaces, design patterns, and more.

Software QA testing training, Java Training, HP UFT training, HP QTP training, Mobile apps testing training,Webservices testing training, SoapUI Testing training, Java, J2EE, ISTQB, BigData training,
Informatica training and many other technologies are having lot of job opportunities.
