Java Exception Handling - without cache block example

You can handle exceptions still without having catch blocks also, only thing you need to do is declare the throws clause in your method signature, so that the calling function would handle the exception. Before throwing exception, it executes the finally block.

Java Exception Handling Sample Code

Code:
package com.myjava.exceptions;

import java.net.MalformedURLException;
import java.net.URL;

public class MyTryBlockOnly {
    public static void main(String a[]) throws MalformedURLException{
        try{
            URL url = new URL("http://www.google.com");
        } finally{
            System.out.println("In finally block");
        }
    }
}

doPost Vs doGet methods
doGet() method is used to get information, while doPost() method is used for posting information. doGet() requests can't send large amount of information and is limited to 240-255 characters. However, doPost()requests passes all of its data, of unlimited length. A doGet() request is appended to the request URL in a query string and this allows the exchange is visible to the client, whereas a doPost() request passes directly over the socket connection as part of its HTTP request body and the exchange are invisible to the client.
