Sometimes a programmer wants to break the normal flow and jump to another statement or execute a set of statements repeatedly.

The statements inside a program are usually executed sequentially. Literals are syntactic representations of boolean, character, numeric, or string data…. Literal in Java represents constant value to be stored in variables. Array is Index based and hence accessing a random element and performing any operations over the elements such as sorting, filling etc, can be easily performed…. Array is index based and the first element of an array starts with the index 0. Operators are classified as Assignment Operator, Arithmetic Operator, Unary Operator, Relational Operator, Logical / Conditional Operator, Bitwise Operator… more… Java – Arrays:Īrray is an object, which stores a group of elements of the same data type. more… Java – Operator:Īn operator is used to perform an operation over one or more operands. Two or more variables of same type can also be declared in a single line separated by commas…. A variable is defined by its name (identifier), type and initialization is optional. Variable is a placeholder (reserved memory block) to store a value of any type. Hence every element to be declared, must strictly define its type. The characters or words or anything which is given in comments section won’t be considered by the Java compiler for compilation process…. So that if another programmer looks at the program, he can easily understand the program by reading the comments. more… Java – Comment:Ĭomments are description given by the programmer within the program. Similarly, by using Person class, we can create objects like Elaya, Dara, Bharath etc…. If you consider creating objects like chair, table, cupboard, then you need to create a class called Furniture. A Class is a blueprint to develop objects. Objects are anything that exists in the world.

Even if it is not defined, compiler would create a one implicitly…. more… Java – Constructors:Ī constructor is a special method in a class, used to initialize the object’s fields.The name of the constructor is same as that of the class name.Whenever a new object of its class is created, a constructor is invoked.Every class has a constructor. There are also static and final modifiers which would be explained later….

Method is defined as the set of code which performs a specific task and returns any data if provided.It is executed, whenever it is invoked.They are used to describe the level of access for the method. This class file is run by the JVM and gives the result. java extension is created and is compiled by Java compiler which yields a class file with.
