This exception is triggered because we may have given an invalid parameter to a Java function. This exception extends the Runtime Exception class, as seen in the diagram below. So, one exception can be triggered when the Java Virtual Machine is running. However, to grasp it completely, have...
The above flow-diagram sums up all you need to know regarding try-catch-finally construct in Java. Summary: When an exception occurs, JVM creates and pass the exception object to the first matching catch block. Once the code within the first matching catch block is executed, if found, the...
