Java try and catch. The try statement allows you to define a block of code to be tested for errors while it is being executed. The catch statement allows you to define a block of code to be executed, if an error occurs in the try block. The try and catch keywords come in pairs:

If an exception occurs within the try block, that exception is handled by an exception handler associated with it. To associate an exception handler with a try block, you must put a catch block after it; the next section, The catch Blocks, shows you how.

The try...catch block in Java is used to handle exceptions and prevents the abnormal termination of the program. Here's the syntax of a try...catch block in Java. try{ // code } catch(exception) { // code } The try block includes the code that might generate an exception.

This section describes how to use the three exception handler components — the try, catch, and finally blocks — to write an exception handler.

This is the syntax for try/catch: try { //Code here } catch (ExceptionHere name) { //Replace ExceptionHere with your exception and name with the name of your exception. //Code if exception "ExceptionHere" is thrown. The code after the try block will be attempted to be run.

Jan 12, 2025 · In this tutorial, we will understand try-catch block in Java with the help of example programs. In the previous tutorial, we have known that when an error occurs within a method of program, the method creates an exception object and hand over it to the runtime system (JVM).

In this guide, we’ll dive deep into how try-catch in Java works, its syntax, best practices, and practical examples. Handling exceptions properly is essential to build resilient and user-friendly applications.
