Common Runtime Error QuestionLevel: BeginnerFocus: Basic concepts, runtime errorsHere’s a piece of code that has been saved in a file called "JollyMessage.java": // A jolly message is written to the screen! class Jollymessage { public compile time error static void main(String[] args) { //Write the message to the terminal window System.out.println("Ho Ho Ho!"); } } The above code will produce a runtime error message. To put it another way, a mistake has been made but it won’t be picked up when the program is compiled, only when it is run. What is the mistake and what error will be returned when the compiled code is executed?To get the most out of this question try and figure out the answer before coming back to read the solution on the next page.

error? At compile time, when the code does not comply with the Java syntactic and semantics rules as described in Java Language Specification (JLS), compile-time errors will occurs. The goal of the compiler is to ensure the code is compliant with these rules. Any rule-violations detected at this stage are reported as compilation errors. The best way to get to know those rules is to go through all the sections in the JLS containing the key words "compile-time error". In general, these rules include syntax checking: declarations, expressions, lexical parsing, file-naming conventions etc; exception handling: for checked exceptions; accessibility, type-compatibility, name resolution: checking to see all named entities - variables, classes, method calls etc. are reachable through at least one of the declared path; etc. The following are some common compile time errors: a class tries to extend more than one class overloading or overriding is not implemented correctly attempt to refer to a variable that is not in the scope of the current block an inner class has the same name as one of one of its enclosing classes a class contains one or more abstract methods and the class itself is not declared "abstract" a class tries to reference a private member of another class trying to create an instance of an abstract class trying to change the value of an already initialized constant (final member) declare two (class or instance) members with the same name Here is a list of conditions that may cause compile-time errors. When the code compiles without any error, there is still chance that the code will fail at run time. The errors only occurs at run time are call run time errors. Run time errors are those that passed compiler's checking, but fails when the code gets executed. There are a lot of causes may result in runtime errors, such as in
