ShortBuffer hashCode() Method in Java with Examples

Last Updated : 17 Jun, 2019
The hashCode() method of java.nio.ShortBuffer is used to return the hash code for a particular buffer. The hash code of a short buffer depends only upon its remaining elements; that is, upon the elements from position() up to, and including, the element at limit() - 1. Because buffer hash codes are content-dependent, it is inadvisable to use buffers as keys in hash maps or similar data structures unless it is known that their contents will not change. Syntax: 
public int hashCode()
Parameters: The method does not take any parameters. Return Value: The method returns the current hash code of the buffer. Below programs illustrate the use of hashCode() method: Program 1: Java 
// Java program to demonstrate
// compareTo() method
import java.nio.*;
import java.util.*;

public class GFG {

    public static void main(String[] args)
    {
        // create short object and assign value to it
        short shortNum1 = 150;
        Short ShortObj1 = new Short(shortNum1);

        // returns hashcode
        int hcode = ShortObj1.hashCode();
        System.out.println("Hashcode for this Short ShortObj1 = "
                           + hcode);
    }
}
Output: 
Hashcode for this Short ShortObj1 = 150
Program 2: Java 
// Java program to demonstrate
// compareTo() method
import java.nio.*;
import java.util.*;

public class GFG {

    public static void main(String[] args)
    {
        // create short object and assign value to it
        short shortNum1 = 6010;
        Short ShortObj1 = new Short(shortNum1);

        // returns hashcode
        int hcode = ShortObj1.hashCode();
        System.out.println("Hashcode for this Short ShortObj1 = "
                           + hcode);
    }
}
Output: 
Hashcode for this Short ShortObj1 = 6010
