Java Assignment Operators: Examples and Usage

This is a simple example that demonstrates the assignment operators. Copy and paste the following Java program in AssignmentOperator.java file. Compile and run this program

Example of Assignment Operator

 
 public class AssignmentOperator {

   public static void main(String args[]) {
      int a = 5;
      int b = 10;
      int c = 0;

      c = a + b;
      System.out.println("c = a + b = " + c );

      c += a ;
      System.out.println("c += a  = " + c );

      c -= a ;
      System.out.println("c -= a = " + c );

      c *= a ;
      System.out.println("c *= a = " + c );

      a = 10;
      c = 15;
      c /= a ;
      System.out.println("c /= a = " + c );

      a = 10;
      c = 15;
      c %= a ;
      System.out.println("c %= a  = " + c );

      c &= a ;
      System.out.println("c &= a  = " + c );

      c ^= a ;
      System.out.println("c ^= a   = " + c );

      c |= a ;
      System.out.println("c |= a   = " + c );
      c <<= 2 ;
      System.out.println("c <<= 2 = " + c );

      c >>= 2 ;
      System.out.println("c >>= 2 = " + c );

      c >>= 2 ;
      System.out.println("c >>= 2 = " + c );

   }
}

Output

 
c = a + b = 15
c += a  = 20
c -= a = 15
c *= a = 75
c /= a = 1
c %= a  = 5
c &= a  = 0
c ^= a   = 10
c |= a   = 10
c <<= 2 = 40
c >>= 2 = 10
c >>= 2 = 2

Problem in addition of two short datatype

 
 class OperatorAddShortExample{
	public static void main(String args[]){
	short a=10;
	short b=10;
	//a+=b;//a=a+b internally so fine
	a=a+b;//Compile time error because 10+10=20 now int
	System.out.println(a);
  }
}

Output

  
OperatorAddShortExample.java:6: error: incompatible types: possible lossy conversion from int to short
	a=a+b;//Compile time error because 10+10=20 now int
	   ^
1 error

solution of the above problem using type conversion

 
class OperatorAddShortExample{
	public static void main(String args[]){
	short a=10;
	short b=10;
	a=(short)(a+b);//20 which is int now converted to short
	System.out.println(a);
  }
}

Output

  
20
