Error Hierarchy Java

Throwable represent the super class of all exceptions and also Runtime Errors in Java. Exception and its sub-classes represent unusual conditions in a program which is expected to occur but can recover from.

exception hierarchy in java Exception handling is a mechanism to handle runtime errors, so that normal flow of the program can be maintained.

The tree diagram below shows the standard exception and error classes defined in Java, organized in the Java exceptions hierarchy.

In this article, we take a look at Java Exceptions - Java Hierarchy, Handling, and Throwing Exceptions. Stay with us to learn more about Java Exceptions, Features, and top Java testing frameworks.

1. Java Exception API Hierarchy The following diagram describes the class hierarchy of exceptions API in JDK As you can see, Throwable is at the top of the hierarchy. It is the supertype of all exceptions and errors in Java. Below Throwable, there are 3 subtypes

In this article, we will learn the exceptions class hierarchy in java.lang package. The objects that inherit from the Throwable class include direct descendants objects that inherit directly from the Throwable class and indirect descendants objects that inherit from children or grandchildren of the Throwable class.

Exception handling in Java allows developers to manage runtime errors effectively by using mechanisms like try-catch block, finally block, throwing Exceptions, Custom Exception handling, etc. An Exception is an unwanted or unexpected event that occurs during the execution of a program, i.e., at runtime, and disrupts the normal flow of the program's instructions. It occurs when something

Master Java exception handling, understand exception hierarchy in Java, and learn practical techniques for catching and managing exceptions effectively.

The Foundation Throwable At the base of the Java exception hierarchy sits the Throwable class. Everything throwable, whether an exception or an error, extends this class.

In Java programming, Throwable class is the root of exception hierarchy and is an immediate subclass of Object class. Let's understand the Java exception hierarchy, as shown in the below figure.
