August 29, 2014 - It must be followed by either a catch or finally or both blocks. try{ //block of statements }catch(Exception handler class){ } ... The catch block is used for the exception handler. It is used after the try block. try{ //block of statements }catch(Exception handler class){ } class ArithmaticTest{ ...

Something went wrong. The 'try catch' is finished.

July 23, 2025 - 3. Exception doesn't occur in try-block: In this case catch block never runs as they are only meant to be run when an exception occurs. finally block(if present) will be executed followed by rest of the program.

If the type of exception that occurred is listed in a catch block, the exception is passed to the catch block much as an argument is passed into a method parameter. The following is an array declared with 2 elements. Then the code tries to access the 3rd element of the array which throws an exception. // File Name : ExcepTest.java import java.io.*; public class ExcepTest { public static void main(String args[]) { try { int a[] = new int[2]; System.out.println("Access element three :" + a[3]); } catch (ArrayIndexOutOfBoundsException e) { System.out.println("Exception thrown :" + e); } System.out.println("Out of the block"); } }

The exception is propagated up the call stack like this until some method catches the exception, or the Java Virtual Machine does. You can attach a finally-clause to a try-catch block.

public void writeList() throws IOException { try (FileWriter f = new FileWriter("OutFile.txt"); PrintWriter out = new PrintWriter(f)) { for (int i = 0; i < SIZE; i++) { out.println("Value at: " + i + " = " + list.get(i)); } } } The try-with-resources statement automatically releases system resources when no longer needed.

August 29, 2022 - When we have nested catch blocks, as soon as a catch matches the exception thrown, it executes the code inside it and then other catch blocks are ignored by the execution. The finally block (if present) is then executed and the execution continues. ...

June 3, 2025 - import java.util.*; public class Geeks { public static void main(String[] args) { try { // Outer try block System.out.println("Outer try block started"); try { // Inner try block 1 int n = 10; int res = n / 0; } catch (ArithmeticException e) { System.out.println ("Caught ArithmeticException in inner try-catch: " + e); } try { // Inner try block 2 String s = null; System.out.println(s.length()); } catch (NullPointerException e) { System.out.println ("Caught NullPointerException in inner try-catch: " + e); } } catch (Exception e) { // Outer catch block System.out.println ("Caught exception in outer try-catch: " + e); } finally { // Finally block System.out.println("Finally block executed"); } } }

The catch statement allows you to define a block of code to be executed, if an error occurs in the try block. The finally statement lets you execute code, after try and catch, regardless of the result.

January 3, 2025 - This comprehensive guide covers 21 unique combinations of try, catch, and finally. With these examples, you’ll gain a thorough understanding of Java’s exception handling mechanisms and avoid common pitfalls.

The try keyword is essential for exception handling in Java, helping to manage runtime errors and maintain the normal flow of the application. try { // Code that may throw an exception } catch (ExceptionType1 e1) { // Code to handle ExceptionType1 } catch (ExceptionType2 e2) { // Code to handle ExceptionType2 } finally { // Code that will always execute }

Here, the size of the array is 5 and the last element of the array is at list[4]. However, we are trying to access elements at a[5] and a[6]. Hence, the code generates an exception that is caught by the catch block. Since the finally block is always executed, we have included code to close the PrintWriter inside the finally block.

April 1, 2025 - In this tutorial, we will discuss the various keywords used in Java for Exception Handling such as Try, Catch, Finally, Throw and Throws with examples.

A finally block should immediately follow the last catch block (or it must immediately follow the try block if there is no catch). Let's look at the simple example where an unchecked exception is caught.

February 25, 2025 - This concludes our discussion on exception handling in java. We have started with the basics of exception handling and exception hierarchy and then we got introduced to handling exceptions using try-catch-finally block. We also learned how to create custom exceptions and how to manually throw an exception.
