Encode and Decode Example in Java

This post demonstrates the how to encode and decode the String data.

package com.ranga;

import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.net.URLEncoder;

/**
 * This class is used to encode and decode the string data.

public class EncodeAndDecodeExample {
    private static final String data = "Hello, I am Ranga Reddy. ";

    public static void main(String[] args) {

        String encodedData = getEncodedData(data);
        System.out.println("Encoded Data: " + encodedData);

        String decodedData = getDecondedData(encodedData);
        System.out.println("Decoded Data: " + decodedData);
    }

    private static String getDecondedData(String encodedData) {
        try {
            return URLDecoder.decode(encodedData, "UTF-8");
        } catch (UnsupportedEncodingException exception) {
            throw new RuntimeException("Does not support UTF-8");
        }
    }

    private static String getEncodedData(String data) {
        try {
            return URLEncoder.encode(data, "UTF-8");

        } catch (UnsupportedEncodingException exception) {
            throw new RuntimeException("Does not support UTF-8");
        }
    }
}

Output:

Encoded Data: Hello%2C+I+am+Ranga+Reddy.+
Decoded Data: Hello, I am Ranga Reddy.
