operators in java

• An operator is basically a symbol or token,which performs arithmethical or logical operations and gives meaningful result.
• There are following type of operator in java-
1. Arithmetical Operator
2. Relational Operator
3. Logical Operator
4. Bitwise Operator
5. Assignment Operator
6. Conditional Operator

Arithmetic Operator

• The operator,which are applied to perform arithmetical calculation in a program,are known as Arithmetical Operations.
• Arithmmetic operator are of 3 type-
1. Unary Operator
2. Binary Operator
3. Ternary Operator
• Unary Operator-An arithmetical operator ,which is applied with a single operand is known as Unary Operator.Example-+,-,++,--
• Binary Operator-An arithmetical operator,which deals with two operands, is known as Binary Operator.Example-+,-,*,/ and % etc

Conditional Operator or Ternary Operator

Ternary Operator deal with three operands.It is also called conditional assignment statement because the value assigned to a variable depends upon a logical expression.

Example

a=5,b=3;

max=(a>b)?a:b;

Here,the value 5 is stored in max as a>b is true

// Program using ternary operator

public class TernaryOperator {
	public static void main(String args[]){
		int num1 , num2;
		num1 = 10;
		num2 = (num1 == 1) ? 20: 30;
		System.out.println( "Value of num2 is : " +  num2 );
		num2 = (num1 == 10) ? 20: 30;
		System.out.println( "Value of num2 is : " + num2 );
	}
}

Output

Value of num2 is : 30
Value of num2 is : 20

// Program to perform bitwise operation

public class bitwiseoperation{
public static void main(String args[])
{
int a,b;
a=12;b=10;
int n = 35,m;

m=~n;
System.out.println("complement is ="+m);
System.out.println("(a&b)="+(a&b));
System.out.println("(a|b)="+(a|b));
System.out.println("(a^b)="+(a^b));
System.out.println("(a<<b)="+(a<<b));
System.out.println("(12>>2)="+(12>>2));
System.out.println("(14>>>2)="+(14>>>2));
}
}

complement is =-36
(a&b)=8
(a|b)=14
(a^b)=6
(a<<b)=48
(a>>b)=3
(a>>>b)=3
