title: Unable to view complete java source code in IntelliJ
body: <p>Earlier I used Eclipse. Recently I have started using IntelliJ. I found that the IntelliJ equivalent of Eclipse keyboard shortcut <kbd>F3</kbd> (view source) is <kbd>F4</kbd>.</p>
  
  <p>But, when I use that I get the source in the following format. </p>
  
  <p><img src="https://i.stack.imgur.com/n7Ur1.png" alt="enter image description here"></p>
  
  <p>It does not show complete source, i.e method implementation is not being shown. I have placed src.zip in the java sdk folder where Java is installed. I have added the src.zip in the project libraries too. In eclipse I can just attach source if it can't find one.</p>
  
  <p>I have seen answers of relevant questions but couldn't follow. So,
  <strong>How to attach the Java source in IntelliJ?</strong></p>
  
  <p>Detailed answer will be appreciated.</p>
  
  <p>Thanks in advance.</p>
