Re: Rational 15 Years Ago by harry010 So you want to know how to call non static methods. Since these methods are not static, they need to be invoked [I]on[/I] an object instance of the calling method's class. You can do something like this: [CODE]Rational num = new Rational( 1, 2 ); System.out.println( num.toDouble() );[/CODE] Its the same idea for the other methods.
