Operators in Java

In this article Operators in Java we give the information about Operators and keywords play a very important role in Java. Such as Arithmetic Operators, Relational Operators, etc.

Operators in Java:

Operators and keywords play a very important role in Java.

1. Operators

Operators are symbols that are used to perform actions or calculations. These are used to change or compare the value of a variable.

Types of Major Operators:

1. Arithmetic Operators: These operators are used for arithmetic calculations.

1. • + :  Addition
   • – : Subtraction
   • * : Multiplication
   • / : Division
   • % : Modulus

2. Relational Operators: These operators establish a relationship between two values.

1. • == : Equal to
   • != : Not equal to
   • > : Greater than
   • < : Less than
   • >= : Greater than or equal to
   • <= : Less than or equal to

3. Logical Operators: These operators are used for logical operations.

1. • && : Logical AND
   • || : Logical OR
   • ! :Logical NOT

4. Assignment Operators: These operators are for assigning value to the variable.

1. • = : Assignment
   • += : Add and assign
   • -= : Subtract and assign
   • *= : Multiply and assign
   • /= : Divide and assign

5. Increment and Decrement Operators: These operators are used to increase or decrease the value of the variable by 1.

1. • ++ :Increment
   • — : Decrement

6. Bitwise Operators: These operators are for performing operations at bit level.

1. • & : AND
   • | : OR
   • ^ : XOR
   • ~ : NOT
   • << : Left shift
   • >> :Right shift

2.Keywords

Keywords in Java are special reserved words that are used to define a particular function or structure. We cannot use these as names of our own variables or methods.

Major keywords:

1. Control Statements:
   • if : If condition
   • else : Else condition
   • switch : Switch case
   • case : Case
   • for : For loop
   • while : While loop
   • do : Do-while loop
   • break : Break loop
   • continue : Continue loop
2. Class Definition :
   • class : Defines a class
   • interface : Defines an interface
   • extends : Inheritance
   • implements : Implements interface
3. Access Modifiers :
   • public : Accessible to all
   • private : Accessible within the class
   • protected : Accessible within package and subclasses
   • final : Cannot be changed
4. Object Oriented Keywords:
   • new : Creates a new object
   • this : Refers to current object
   • super : Refers to superclass
   • static : Static method or variable
   • abstract : Abstract class or method
5. Exception Handling :
   • try : Try block
   • catch :Catch block
   • finally : Finally block
   • throw : Throw exception
   • throws : Declare exception
6. Miscellaneous :
   • void : No return type
   • return : Returns a value
   • import : Imports a package
   • package : Defines a package
   • null :Null value
   • true : True boolean value
   • false : False boolean value

These were some of the major operators and keywords of Java, which are used in any Java programming language.
