ASWEB - Avoid Statements With Empty Body

As far as possible avoid statements with empty body.

Wrong

`StringTokenizer st = new StringTokenizer(class1.getName(), ".", true);
String s;
for( s = ""; st.countTokens() > 2;
s = s + st.nextToken() );`

Tip: Provide statement body or change the logic of the program (for example, use `while` statement instead of `for` statement)

Right

`StringTokenizer st = new StringTokenizer(class1.getName(), ".", true);
String s = "";
while( st.countTokens() > 2 ) {
s += st.nextToken();
}`
