  • Ternary operator also known as conditional operator in java.
  • Ternary operator used to evaluate boolean expression and it consists of three operands.




Ternary operator in java syntax:

  1. variable x = (expression) ? value if true : value if false

  • Value of x will be decided based on the condition. if condition is true then it assigns first value to the variable
  • If Expression is false then it assigns second value to the variable.

Java simple example program on ternary operator / conditional operator in java


  1. package operatorsinjava;
  2. public class TernaryOperator {
  3.  
  4.     /**

  6.      * 
  7.      */
  8.  public static void main(String[] args) {
  9.         
  10.  // checking condition 2>3 and if true assign 3 else 3
  11.   int x= (2>3)?3:2;
  12.         
  13.   System.out.println(x);
  14.         
  15.  // checking condition 5<4 if true assign 4 else 3
  16.  int y= (5<4)?4:3;
  17.         
  18.  System.out.println(y);
  19.  
  20. }
  21.

Output:

  1. 2
  2. 3
