Pointless boolean expression

Reports unnecessary or overly complicated boolean expressions.

Such expressions include &&-ing with true, ||-ing with false, equality comparison with a boolean literal, or negation of a boolean literal. Such expressions can be simplified.

Example:

  boolean a = !(x && false);
  boolean b = false || x;
  boolean c = x != true;

After the quick-fix is applied:

  boolean a = true;
  boolean b = x;
  boolean c = !x;
