provide if statement with a Boolean expression that evaluates to true.
why it is not work ?
Your if and your main method is O.K. ;). But the definition and the name of your class is wrong.
"public class Ifpublic class If " a class name in Java starts with a capital letter and has no spaces. So it would like something like this public class Test{}. and not public class ifpublic class if{}.
