TIOBE - Java Coding Standard

Rule: Naming18

Synopsis:	Avoid naming non-fields with a member-like prefix
Language:	Java
Severity Level:	7
Category:	Naming

Description:

Detects when a non-field has a name starting with 'm_' or 'mX', where 'X' is any uppercase character. This usually indicates a field and thus is confusing.

public class Foo {
    private int m_foo; // OK
    public void bar(String m_baz) {  // Bad
      int mBar = 42; // Bad
    }
  }
