Hashcode of an int

Question

What is the hashcode of a primitive type, such as int?

for example, let\'s say num was an interger.

int hasCode = 0;

if (num != 0) {
  hasCode = has         


        

Answer 1

The java.lang.Integer.hashCode() method returns a hash code value for primitive value of int but represented as an Integer object.

/**
 * Returns a hash code value for an Integer,
 * equal to the primitive int value it represents.
 */
public class IntegerDemo {

    public static void main(String[] args){
        Integer i = new Integer("20");
        System.out.println("Value = " + i.hashCode());
    }

}`

Results:

Value = 20
