Uncaught Exception

Catching one of Java’s standard exceptions, as the preceding program does, has a side benefit: It prevents abnormal program termination. When an exception is thrown, it must be caught by some piece of code, somewhere. In general, if your program does not catch an exception, then it will be caught by the JVM. The trouble is that the JVM’s default exception handler terminates execution and displays a stack trace and error message.Example as:

class ExceptionUncaught {
public static void main(String args[]) {
System.out.println(3/0);
}
}
