Boolean.hashCode() Method in Java

Description

Program to get hash code for Boolean object. We are using hashCode() method of Boolean class for this purpose, it returns integer 1231 if this object represents true; returns the integer 1237 if this object represents false.

Example

class BooleanHashCodeEx {

   public static void main(String[] args) {

      // Boolean objects
      Boolean bObj, bObj2;

      // Assigning values to both the objects
      bObj = new Boolean(true);
      bObj2 = new Boolean(false);

      // integers to store hash code
      int icode, icode2;

      // Getting Hash Code
      icode = bObj.hashCode();
      icode2 = bObj2.hashCode();

      // Displaying HashCode for both the objects
      System.out.println("Hash code of "+bObj+" is "+icode);
      System.out.println("Hash code of "+bObj2+" is "+icode2);
   }
}

Output:

Hash code of true is 1231
Hash code of false is 1237

public int hashCode(): Returns a hash code for this Boolean object. It returns the integer 1231 if this object represents true; returns the integer 1237 if this object represents false.
