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");
        }
    }
}
