title: jar edit and re-compile in simple way
body: <p>I have a jar file called ScreenCapture.jar</p>
  
  <p>I use <a href="http://jd.benow.ca/" rel="noreferrer">http://jd.benow.ca/</a> what is in there. I have even downloaded jd-gui</p>
  
  <p>This is what it shows me</p>
  
  <p><img src="https://i.stack.imgur.com/AS9Fp.png" alt="screenCapture"></p>
  
  <p>I can see the ScreenCapture.class file. I want to edit 2 lines here</p>
  
  <pre><code>      Thread.sleep(15000L);
        to
        Thread.sleep(60000L);
  </code></pre>
  
  <p>and </p>
  
  <pre><code>driver.manage().window().setSize(new Dimension(1024, 768));
  to
  driver.manage().window().setSize(new Dimension(1200, 800));
  </code></pre>
  
  <p>But this file is not editable.</p>
  
  <p>My question is, how to edit it? like how to decompile it so I can edit it and then recompile it. So I can just re-upload my jar file and everything gets back to normal?</p>
  
  <p>Btw, I know nothing about java, and I don't have any special application/software installed on my machine</p>
