When coding Java classes and interfaces, the following formatting rules should be followed:
* No space between a method name and the parenthesis "(" starting its parameter list
* Open brace appears at the end of the same line as the declaration statement
* Closing brace starts a line by itself indented to match its corresponding opening statement, except when it is a null statement the "}" should appear immediately after the "\{"
* Methods are separated by a blank line
E.g.,
{code}
class Sample extends Object {
    int ivar1;
    int ivar2;
    Sample(int i, int j) {
        ivar1 = i;
        ivar2 = j;
    }
    int emptyMethod() {}
    ...
}
{code}
