title: method argument is not accessible by name inside method
body: <p>Is it a bug in android studio or java, don't know. I was working on an astronomy application. I have created a method to get phase of moon. It takes two argument but only one argument is accessible by name. In debugger it says argument not found but when I assign to some other variable, it gets assigned. No runtime error in execution.

  <p>Argument that is not accessible is <code>moon_degrees</code> but when I assign it's value to <code>variable moon_degree</code> it works. </p>
  
  <p>Don't know what's happening</p>
