JAVA

In this boolean method I want to detect if the input from command line args are pure letters and two symbols "," and "."

For output below, the command line args:

(abc "" def) and (Hello.World) are both detected as true but it should be false.

I suppose the period should add a space after it or it will return false, and for "" I have no idea of how to detect it and return false.

Please help me adjust my code to get rid of this problem.
