Local variable hides field

Reports local variables named identically to a field of a surrounding class. As a result of such naming, you may accidentally use the variable where the identically named field is intended.

A quick-fix is suggested to rename the variable.

Example:

public class Foo {
  public Object foo;

  void bar() {
    Object o = new Object() {
      void baz() {
        Object foo; // Local variable 'foo' hides field in class 'Foo'
      }
    };
  }
}

You can configure the following options for this inspection:

Ignore non-accessible fields - ignore local variables named identically to superclass fields that are not visible (for example, because they are private).
Ignore local variables in a static context hiding non-static fields - for example when the local variable is inside a static method or inside a method which is inside a static inner class.
