The boolean Type In Java

The boolean type has two values, false and true. It is used for evaluating logical conditions. You cannot convert between integers and boolean values.

* Note: In C++, numbers and even pointers can be used in place of boolean values. The value 0 is equivalent to the bool value false, and a non-zero value is equivalent true. This is not the case in Java. Thus, Java programmers are shielded from accidents such as

 if (x = 0) // oops... meant x == 0

In C++, this test compiles and runs, always evaluating to false. In Java, the test does not compile because the integer expression x = 0 cannot be converted to a boolean value.

* Example:
=> File: booleanType.java

 package com.webmobileaz;

import java.util.Scanner;

public class booleanType {
 public static void main (String []args) {
  
  Scanner scran = new Scanner(System.in);
  boolean b = scran.nextBoolean();
  if(b == true) {
   System.out.println("Hello!");
  } else {
   System.out.println("Hehe Hihi!");
  }
 }
}

=> Result:
(1). If you input: true

 Hello!

(2). If you input: false

 Hehe Hihi!

(3). Other -> Exception
