PIIFS - Provide Incremental In For-Statement or use while-statement

Checks if third argument of the for-statement is missing.

Wrong

`for ( Enumeration enum = getEnum(); enum.hasMoreElements(); ) {
Object o = enum.nextElement();
doSomeProc(o);
}`

Tip: Either provide incremental part of a for-structure or cast for-statement into a while-statement.

Right

`Enumeration enum = getEnum();
while (enum.hasMoreElements()) {
Object o = enum.nextElement();
doSomeProc(o);
}`
