public class Assert

extends Object

Class for assertions. Programmers can use this to raise runtime exceptions if they like. Use code like

Assert.isEqual( obj1, obj2 );

If you use code like

Assert.isTrue( Assert.ON && test );

Then the code will only run if the ON constant is true (so we can turn it off for production code).
