Java Try Catch Blocks

In this Java article we want to learn about Java Try Catch Blocks, Java is popular programming language and that is used for developing different types of applications. if you are a programmer than you will know that in any programming language errors and exceptions can occur, so the same will be in Java programming language. for handling such situations, Java provides a way called try catch blocks. in this article we want to explore what try catch blocks are and how they can be used in Java programming.



What are Java Try-Catch Blocks ?

So try catch block is a structure used to catch and handle exceptions in Java. try block contains the code that might throw an exception, and catch block contains the code that handles the exception. in a programming if an exception is thrown in the try block, catch block is executed, and the program can recover from the exception.



So now let’s talk about the syntax of try catch block, this is the syntax.

So in the above code try block contains the code that might throw an exception. if an exception is thrown, Java will look for a catch block that can handle exception. catch block specifies the type of exception that it can handle. if the exception type matches the type of the exception thrown in the try block, the catch block is executed.



Handling Multiple Exceptions in Java

Java allows handling multiple exceptions in single try catch block. this can be useful when you want to handle different types of exceptions in different ways. this is the syntax for handling multiple exceptions:




Java also provides finally block that can be used to execute code regardless of whether an exception is thrown or not. this is the syntax for try catch finally block:




Now let’s create a practical example, for example we have a program that reads data from a file and processes it. but if file is not found or cannot be read, our program should handle the exception and notify the user.
