title: locate imports definition in java
body: <p>I'm a newbie in java. Is there any way to find the required imports(or missing imports) in java programming?. I know that in modern editor like Eclipse and Netbeans. But we have to do java in notepad  for examination, that's why. </p>
  
  <p>For example, When I use Jframe, I want to know which is the required imports. Is it possible to locate 'import's definition in a directory or file?</p>
