Program: How to find user defined objects from HashSet?

Below example shows how to search user defined objects from HashSet. You can achieve this by implementing equals and hashcode methods at the user defined objects.

package com.java2novice.hashset;

import java.util.HashSet;

public class MyHashSetSearchObject {

	public static void main(String a[]){
		
		HashSet<Price> lhs = new HashSet<Price>();
		lhs.add(new Price("Banana", 20));
		lhs.add(new Price("Apple", 40));
		lhs.add(new Price("Orange", 30));
		for(Price pr:lhs){
			System.out.println(pr);
		}
		Price key = new Price("Banana", 20);
		System.out.println("Does set contains key? "+lhs.contains(key));
	}
}

class Price{
	
	private String item;
	private int price;
	
	public Price(String itm, int pr){
		this.item = itm;
		this.price = pr;
	}
	
	public int hashCode(){
		System.out.println("In hashcode");
		int hashcode = 0;
		hashcode = price*20;
		hashcode += item.hashCode();
		return hashcode;
	}
	
	public boolean equals(Object obj){
		System.out.println("In equals");
		if (obj instanceof Price) {
			Price pp = (Price) obj;
			return (pp.item.equals(this.item) && pp.price == this.price);
		} else {
			return false;
		}
	}
	
	public String getItem() {
		return item;
	}
	public void setItem(String item) {
		this.item = item;
	}
	public int getPrice() {
		return price;
	}
	public void setPrice(int price) {
		this.price = price;
	}
	
	public String toString(){
		return "item: "+item+"  price: "+price;
	}
}
