Constant on wrong side of comparison

Reports comparison operations where the constant value is on the wrong side.

Some coding conventions specify that constants should be on a specific side of a comparison, either left or right.

Example:

boolean compare(int x) { return 1 > x; // Constant '1' on the left side of the comparison }

After the quick-fix is applied:

boolean compare(int x) { return x < 1; }

Use the inspection settings to choose the side of constants in comparisons and whether to warn if null literals are on the wrong side.
