Java ternary, three-way, ? Operator expression

Question

What is the output of the following code 


class Main { //from  w  w  w. ja va2 s  .c o m
 
  public static void main(String args[])  
  { 
    int a = 1;
    int b = a ? 2:3;
    
    System.out.println(b);
  } 
}



Type mismatch: cannot convert from int to boolean

Note

In Ternary, three-way, ? Operator expression: 


expression1 ? expression2 : expression3

expression1 must evaluate to a boolean value.

We can fix it by: 

class Main { // www . ja v a  2 s.c  om
 
  public static void main(String args[])  
  { 
    int a = 1;
    int b = a==1 ? 2:3;
    
    System.out.println(b);
  } 
}
