Java boolean cast to int

Question

What is the output of the following code: 

public class Main{

  public static void main(String[] args) {
    int i = 0;//from w w  w  . ja  va2 s  .c o m
    i = i+ 1;
    boolean n = (boolean)i;
    System.out.println(i);
    System.out.println(n);
    
    
  }

}



Compile time error:
Cannot cast from int to boolean

Note

Cast can only be used to cast compatible types

int 0 or 1 cannot represent boolean value in Java.

Check the following tutorial: [Type Conversion and Casting](Java Type Conversion and Casting).

We can use logic to convert all positive int value to true. 

public class Main {
  public static void main(String args[]) {
     int i = 5;/*  www.  jav a 2 s  .c om*/
     
     boolean b = false;
     
     if(i > 0) {
        b = true;
     }
     System.out.println(b);
  }
}
