Unary plus
Reports usages of the + unary operator. The unary plus is usually a null operation, and its presence might represent a coding error. For example, in a combination with the increment operator (like in +++) or with the equal operator (like in =+).
Example:
The following quick fixes are suggested:
Remove
+operators before theivariable:void unaryPlus(int i) { int x = i; }Replace
+operators with the prefix increment operator:void unaryPlus(int i) { int x = ++i; }
