Java Operators

What are operators and its types in Java?

Operators are the symbols which perform the operation on the some values. These values are known as operands. Java have following operators –

• Arithmetic Operators
• Relational Operators
• Logical Operators
• Assignment Operators
• Bitwise Operators
• Misc Operators

1. Arithmetic Operators

2. Relational Operators

It is also known as comparison operator because it compares the values. After comparison it returns the Boolean value i.e. either true or false.

3. Logical Operators

4. Assignment Operator

5. Bitwise Operators

It performs bit by bit operation. Suppose there are two variable I = 10 and J = 20 and their binary values are

I = 10 = 0000 1010
J = 20 = 0001 0100

Misc Operators

Some misc operators are:
1. Conditional Operator ( ? : )
It is also known as ternary operator that means it consists of three operands and performs Boolean expression.
Syntax

variable i = (condition) ? value1 (if condition is true) : value2( if condition is false)

e.g.

public class Intellipaat {
public static void main(String args[]){
int i, j;
i = 20;
j = (i <=50) ? 20: 60;
System.out.println( "Value of j is : " +  j );
}
}

Compile and execute above program.
Output

alue of j is : 20

2. instanceof Operator:
It is used only for object reference variables. It checks that whether the object is of interface type or class type.
Syntax:

(Object_reference_variable ) instanceof  (interface/class type)

e.g.

public class Intellipaat {
public static void main(String args[]){
String name = "intellipaat";
boolean outcome = name instanceof String;
System.out.println( outcome );
}
}

Compile and execute above program.
Output
true
It returns true because name is a type of String.
