'String.equals()' called with 'CharSequence' argument

Reports calls to String.equals() with a CharSequence as the argument.

String.equals() can only return true for String arguments. To compare the contents of a String with a non-String CharSequence argument, use the contentEquals() method.

Example:

boolean equals(String s, CharSequence ch) { return s.equals(ch); }
boolean equals(String s, CharSequence ch) { return s.contentEquals(ch); }
