User-defined Exception: In Java, built-in exceptions handle general scenarios, but user-defined exceptions are helpful when specific conditions require custom error handling. These exceptions can be created by extending the Exception class and throwing them with the throw keyword. Below is an example...
Exception handling cancatchandthrowexceptions. If a detecting function in a block of code cannot deal with an anomaly, the exception is thrown to a function that can handle the exception. A catch statement is a group of statements that handle the specific thrown exception.Catch parametersdetermine...
The program must be able to handle exceptions so its current operation -- disrupted due to the exception -- can finish without further problems or errors.

Exception propagation in Java - an exception is first thrown from the top of the stack and if it is not caught, it drops down the call stack to the previous method. After a method throws an exception, the runtime system attempts to find something to handle it. The set of possible "som...

Figure 1: Multiple threads of a Java program have their own stack but share the heap memory of the JVM. A question that often comes up is how is a Java thread different from a Java process. A Java process is a program in execution. A Java thread is a subset of a Java process. ...
The exception handler chosen is said to catch the exception. If the runtime system exhaustively searches all the methods on the call stack without finding an appropriate exception handler, as shown in the next figure, the runtime system (and, consequently, the program) terminates. Searching the...
