would say that the use of an uninitialized variable's value in Java code is a syntax error, but many others would disagree[1][2] and would classify this as a (static) semantic error. In 8-bit home computers that used BASIC interpreter as their primary user interface, the SYNTAX ERROR error message became somewhat notorious, as this was runtime error definition the response to any command or user input the interpreter couldn't parse. A syntax error may also occur when an invalid equation is entered into a calculator. This can be caused, for instance, by opening brackets without closing them, or less commonly, entering several decimal points in one number. In Java the following is a syntactically correct statement: System.out.println("Hello World"); while the following is not: System.out.println(Hello World); The second example would theoretically print the variable Hello World instead of the words Hello World. However, a variable in Java cannot have a space in between, so the syntactically correct line would be System.out.println(Hello_World). A compiler will flag a syntax error when given source code that does not meet the requirements of the language grammar. Type errors (such as an attempt to apply the ++ increment operator to a boolean variable in Java) and undeclared variable errors are sometimes considered to be syntax errors when they are detected at compile-time. However, it is common to cl

of errors: syntax errors, runtime errors, and logic errors. Syntax errors These are errors where the compiler finds something wrong with your program, and you can't even https://www.cis.upenn.edu/~matuszek/General/JavaSyntax/errors.html try to execute it. For example, you may have incorrect punctuation, or may http://www.dickbaldwin.com/alice/Alice0155.htm be trying to use a variable that hasn't been declared. Syntax errors are the easiest to find and correct. The compiler will tell you where it got into trouble, and its best guess as to what you did wrong. Usually the error is on the exact line indicated by the compiler, or the line syntax error just before it; however, if the problem is incorrectly nested braces, the actual error may be at the beginning of the nested block. Runtime errors If there are no syntax errors, Java may detect an error while your program is running. You will get an error message telling you the kind of error, and a stack trace that tells not only where the error occurred, but also of syntax error what other method or methods you were in. For example, Exception in thread "main" java.lang.NullPointerException at Car.placeInCity(Car.java:25) at City.
Programming Notes # 155 Preface General Viewing tip Supplementary material Discussion Syntax errors Runtime errors Logic errors Summary What's next? Lab project Resources Copyright About the author Preface This tutorial lesson is part of a series designed to teach you how to program using the Alice programming environment under the assumption that you have no prior programming knowledge or experience. Have some fun Because Alice is an interactive graphic 3D programming environment, it is not only useful for learning how to program, Alice makes learning to program fun. Therefore, you should be sure to explore the many possibilities for being creative provided by Alice while you are learning to program using these tutorials. And above all, have fun in the process of learning. General In the previous lesson titled "Class-Level Methods and Inheritance" I taught you how to: Write and use class-level methods. Extend an existing class into a new class that represents a more specialized type of object than the objects created from the original class. Create objects from the new class and add them to your world. Add your new class to the gallery. Create new folders in the gallery to serve as repositories for your new classes. In this lesson, I will teach you about syntax errors, runtime errors, and logic errors, as well as some of the ways to avoid them. Viewing tip I recommend that you open another copy of this document in a separate browser window and use the following links to easily find and view the figures while you are reading about them. Figure 1. Result of dividing by zero. Figure 2. Error message from dividing by zero. Supplementary material Once you have mastered Alice, I recommend that you also study the other lessons in my extensive collection of online programming tutorials. You will find a consolidated index at www.DickBaldwin.com. Discussion There are at least three kinds of errors that you can encounter when writing computer programs: Syntax errors Runtime errors Logic errors Syntax errors Syntax or format errors are a major problem for most beginning programmers using languages such as C++, Java, and C#. A syntax error occurs when the programmer fails to obey one of the grammar rules of the language. Typically this involves things like using the wrong case, putting punctuation where it is not supposed to be, failing to put punctuation where it is supposed to be, etc. One of the great things about Alice as a programming language f
