relOptr is a relational operator.


Examples of Comparison Operators

Example 1 : Program that displays use of all comparison operators i.e ==, !=, >, <, >= and <=

class CompOptrDemo 
{
   public static void main(String[] args) 
   {
int a = 10, b = 15, c = 15;
System.out.println("Comparison Operators and returned values");
System.out.println(" a > b = " + (a > b)); 
System.out.println(" a < b = " + (a < b)); 
System.out.println(" b >= a = " + (b >= a)); 
System.out.println(" b <= a = " + (b <= a)); 
System.out.println(" b == c = " + (b == c)); 
System.out.println(" b != c = " + (b != c)); 
   }
}


Output

Comparison Operators and returned values
a > b = false
a < b = true
b >= a = true
b <= a = false
b == c = true
b != c = false
