Java URL hashCode() method

The hashCode() method of URL class creates an integer suitable for the hash table indexing. The hash code is based upon all the URL components relevant to the URL comparison. As such, this operation is a blocking operation.

Syntax

Overrides

hashCode in class Object

Returns

a hash code for this URL.

Example 1

import java.net.MalformedURLException;
import java.net.URL;
import java.util.Scanner;

public class URLhashCodeExample1 {
public static void main(String args[]) throws MalformedURLException
{
	
	Scanner s= new Scanner(System.in);
	System.out.println("Enter Url ");
	String url=s.nextLine();
	//creating url object
	URL u=new URL(url);
	//getting hashcode for this url
	System.out.println("  Hashcode for given url object : "+u.hashCode());	

     }	
}

Output:

Enter Url

Hashcode for given URL object : 986473352

Example 2

import java.io.*;
import java.net.*;

public class URLhashCodeExample2 {
public static void main(String args[]) throws IOException
{
	//passing url in constructor
	URL url1=new URL("https://www.javatpoint.com/java-threadpoolexecutor");
	URL url2 =new URL("https://www.javatpoint.com/java-threadpoolexecutor");
	//comparing url with other object
	if(url1.hashCode()==url2.hashCode())
	System.out.println("Both URL Matching");
	else
	System.out.println("Both URL different");	
	BufferedReader br=new BufferedReader(new InputStreamReader(url1.openStream()));
	String in;
	while((in=br.readLine().toString())!=null)
	{ 
		System.out.println(in);
	}
	br.close();}
}
