Blank spaces

A single blank space (not tab) should be used:

1. Between a keyword and its opening parenthesis. This applies to the following keywords: catch,for, if, switch, synchronized, while. It does not apply to the keywords super and this.
2. After any keyword that takes an argument. Example: return true;
3. Between two adjacent keywords.
4. Between a keyword or closing parenthesis, and an opening brace "{".
5. Before and after binary operators3 except .(dot).
6. After a comma in a list.
7. After the semicolons in a for statement, e.g.: for (expr1; expr2; expr3) {

Blanks should not be used:

1. Between or after a 'dot' operator.
2. Between a unary operator and its operand.
3. Between a cast and the expression being casted.
4. After an opening parenthesis or before a closing parenthesis.
5. After an opening square bracket [ or before a closing square bracket ]. Examples:

         a += c[i + j] + (int)d + foo(bar(i + j), e);
         a = (a + b) / (c * d);
         if (((x + y) > (z + w)) || (a != (b + 3))) {
              return foo.distance(x, y);
         }
   

Do not use special characters like form-feeds or backspaces.
