Java code breaks

I am trying to post this code to my wordpress blog but the page shows blank.

<pre class="lang:java decode:false">package com.mudassirshahzad;

import java.io.BufferedReader;

	private final String USER_AGENT = "Mozilla/5.0";

	public static void main(String[] args) throws Exception {

		HttpURLConnectionExample http = new HttpURLConnectionExample();

		System.out.println("Testing 1 - Send Http GET request");
		http.sendGet();

		System.out.println("\nTesting 2 - Send Http POST request");
		http.sendPost();

	}

	// HTTP GET request
	private void sendGet() throws Exception {

		String url = "https://www.google.com/search?q=mkyong";

		URL obj = new URL(url);
		HttpURLConnection con = (HttpURLConnection) obj.openConnection();

		// optional default is GET
		con.setRequestMethod("GET");

		//add request header
		con.setRequestProperty("User-Agent", USER_AGENT);

		int responseCode = con.getResponseCode();

		StringBuffer response = new StringBuffer();

		while ((inputLine = in.readLine()) != null) {
			response.append(inputLine);
		}
		in.close();

		//print result
		System.out.println(response.toString());
