Exception Handling in Java Example | Java Exception Handling

In Java, the program that is coded by the programmer can be used in a very unexpected way by the user, due to this, the program may fail in different sort of ways during execution. The main objective of a programmer should be to write a code that does not fail unexpectedly. That unexpected stopping of the program while execution is known as an exception, it disrupts the normal execution flow of a program.

Exception Handling in Java Example

An exception is an event that interrupts the normal flow of execution. It is a disruption during the execution of the Java program. The Exception Handling in Java is one of the powerful mechanisms to handle runtime errors so that the normal flow of the application can be maintained. Let’s see the difference between Error v/s Exception.

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

Java Throws Keyword - DZone Java

The throws keyword in Java allows developers to check their code for invalid entry and prepare further steps if an exception occurs.

Learn about the throws keyword in Java with examples. In simple words, the throws keyword is used to declare an exception. It gives an indication to the developer about the exception that may occur. It is better for the developer to provide the exception handling code so that the normal flow of the program is maintained. There are two ways to handle the code:

  1. Throw an exception that is caught by the try/catch block
  2. Declare an exception in the method signature i.e using the throws keyword

What will happen if you do not handle the code? You will get a compilation error if the exception is a checked exception.

Exception Handling in Java: Contingencies vs. Faults

When and how to use checked and unchecked exceptions

Introduction

Since the invention of the Java language, there has been a long-standing debate about checked versus unchecked/runtime exceptions. Some people argue that checked exceptions promote a better design. Others feel that checked exceptions get in the way, especially as systems mature and refactor over time, and therefore unchecked exceptions are better. The Effective Java Exceptions article settles this debate once and for all: both checked and unchecked exceptions are acceptable, and each has its purpose within an application. I highly recommend reading that article. I will refer back to its concepts and terminology going forward.

Exception Handling in Java [With Examples]

Exceptions are the unwanted and unexpected event of a program that is never desired by a programmer but has to deal with it so many times. The bright side is that it is possible with the object-oriented language Java to mitigate those undesirable events through a concept called ‘Exception Handling in Java’. It does not repair the exception but provides an alternate way to deal with it.

There can be many reasons for an exception to occur including entry of incorrect data, hardware failure, connection failure, server down, etc. Thus, exception handling is and always will be important in the course of learning Java as it helps to assure the normal flow of a program at the time an unexpected event occurs. Ignoring exceptions may cause the entire software to crash and may result in loss of data.

Now that we got an idea about exceptions and exception handling, let’s dive into it in detail and also understand how Java helps in handling exceptions.
