are basically three types of errors that you must contend with when writing computer programs: Syntax errors Runtime errors Logic errors Generally speaking, the errors become more difficult to find and fix as you move down the above list. Syntax errors In effect, syntax errors represent grammar errors in the use of the programming language. Common examples are: Misspelled variable java error inconvertible types and function names Missing semicolons Improperly matches parentheses, square brackets, and curly braces Incorrect format in selection and loop statements Runtime errors Runtime errors occur when a program with no syntax errors asks the computer to do something that the computer is unable to reliably do. Common examples are: Trying to divide by a variable that contains a value of zero Trying to open a file that doesn't exist There is no way for the compiler to know about these kinds of errors when the program is compiled. Logic errors Logic errors occur when there is a design flaw in your program. Common examples are: Multiplying when you should be dividing Adding when you should be subtracting Opening and using data from the wrong file Displaying the wrong message Sample Programs The three sample programs that follow provide simple examples of all three types of errors. A syntax error The program in Listing 1 contains a syntax error that causes the compiler to report a compilation error. Note that this program is written using an object-based fo

Know Your Bugs: Three Kinds of Programming Errors Visual Studio 2008 Other Versions Visual Studio 2005 In this lesson, you will learn about the different types of errors that can occur when writing a program.Even the most experienced programmers make mistakes, and knowing how to debug an application and find those mistakes is an important part of programming. Before you learn about the debugging process, however, it helps to know the types of bugs that you will need to find and fix.Programming errors fall into three categories: compilation errors, run-time errors, and logic errors. The techniques for debugging each of these are covered in the next three lessons.Compilation ErrorsCompilation errors, also known as compiler errors, are errors that prevent your program from running. When you press F5 to run a program, Visual Basic compiles your code into a binary language that the computer understands. If the Visual Basic compiler comes across code that it does not understand, it issues a compiler error.Most compiler errors are caused by mistakes that you make when typing code. For example, you might misspell a keyword, leave out some necessary punctuation, o

When an Exception occurs the normal flow of the program is disrupted and the program/Application terminates abnormally, which is not recommended, therefore, these exceptions are to be handled. An exception can occur for many different reasons. Following are some scenarios where an exception occurs. A user has entered an invalid data. A file that needs to be opened cannot be found. A network connection has been lost in the middle of communications or the JVM has run out of memory. Some of these exceptions are caused by user error, others by programmer error, and others by physical resources that have failed in some manner. Based on these, we have three categories of Exceptions. You need to understand them to know how exception handling works in Java. Checked exceptions − A checked exception is an exception that occurs at the compile time, these are also called as compile time exceptions. These exceptions cannot simply be ignored at the time of compilation, the programmer should take care of (handle) these exceptions. For example, if you use FileRead
