The java.lang.Boolean.hashCode() method returns a hash code for a boolean value which is compatible with Boolean.hashCode().

NA.

Example:

In the example below, the java.lang.Boolean.hashCode() method returns a hash code for the given boolean value.

import java.lang.*;

public class MyClass {
  public static void main(String[] args) {
    
    //creating boolean values
    boolean b1 = true;
    boolean b2 = false;

    //printing hashcode of the boolean values
    System.out.println("hashCode of the b1 is: " + Boolean.hashCode(b1)); 
    System.out.println("hashCode of the b2 is: " + Boolean.hashCode(b2));   
  }
}

The output of the above code will be:

hashCode of the b1 is: 1231
hashCode of the b2 is: 1237
