The hashCode() method of Boolean class is a built in method to return a int hashcode value corresponding to the Boolean object.
Syntax
BooleanObject.hashCode()
Return Type: It returns a int hashcode value corresponding to the Boolean object. It returns 1231 if the Boolean object stores the value true. It returns 1237 if the Boolean object stores the value false.
Below is the implementation of hashCode() method in Java:
Program 1:
// java code to demonstrate// Boolean hashCode() method  class GFG {    public static void main(String[] args)    {          // creating Boolean object        Boolean b = new Boolean(true);          // hashCode method of Boolean class        int output = b.hashCode();          // printing the output        System.out.println(output);    }} |
Output:
1231
Program 2:
// java code to demonstrate // Boolean hashCode() method  class GFG {    public static void main(String[] args)    {          // creating Boolean object        Boolean b = new Boolean(false);          // hashCode method of Boolean class        int output = b.hashCode();          // printing the output        System.out.println(output);    }} |
Output:
1237
