Findings - Overview

code-style SimplifyStartsWith (PMD)

This call to String.startsWith can be rewritten using String.charAt(0)

Since it passes in a literal of length 1, this call to String.startsWith can be rewritten using String.charAt(0) to save some time.

  
public class Foo {
  boolean checkIt(String x) {
      return x.startsWith("a");
  }
}
