If the objects occupied different addresses, but still had the same values stored in variables, then the "is statement" would evaluate to false. http://globalinfoindex.com/logic-error/logic-errors-java.php

Multiplying two numbers instead of adding them together may also produce unwanted results. Because logic errors are often hidden in the source code, they are typically harder to find and debug than syntax errors.

Syntax errors These are errors where the compiler finds something wrong with your program, and you can't even try to execute it.

The Java system, of course, has no idea what your program is supposed to do, so it provides no additional information to help you find the error. davefeinberg 2.310 görüntüleme 11:29 1-8: Syntax and Run-time Errors - Süre: 9:30.

Create objects from the new class and add them to your world. In addition to the many platform and/or language independent benefits of Java and C# applications, he believes that a combination of Java, C#, and XML will become the primary driving force Syntax errors probably won't be a problem for you as long as you are programming using Alice. Since there are a near infinite number of things that fall in this category, there are a near infinite number of ways to write programs that cause runtime errors.
