The if statement evaluates boolean (true or false) expressions. For example:
if ( a = b ) or
if (4 = 4 )
The first would be true if a was equal to b and false if not. The second would always be true seeing that 4 always equals 4.
They do the same thing, but only the former can be used in a Java program.
You never write "do" seperately in Java. The only situation I can think of when you have to write "do" is in the "do while" statement. This is the syntax: do { statement(s) } while (expression);
