Multiple Catch Blocks in Java

Last Updated: 10 July, 2023

In Java, it is possible to have multiple catch blocks following a try block to handle different types of exceptions. This allows you to specify different exception handlers for different types of exceptions that may occur within the try block. The catch blocks are evaluated in order, and the first catch block that matches the type of the thrown exception is executed.

Here's the syntax for using multiple catch blocks in Java::

  try 
  { 
    // code
  } 
  catch(ExceptionType1 ex1) 
  { 
    // code 
  } 
  catch(ExceptionType2 ex2) 
  { 
    // code 
  }
  ......
  ...... 
  catch(ExceptionTypeN exN) 
  { 
    // code 
  }

📝 There is no limit on the number of catch blocks corresponding to a try block.

Flowchart of Multi-catch Block in Java

Syntax:

  try {  
    // code
  } 
  catch (ExceptionType1 | Exceptiontype2 | ExceptiontypeN ex){   
    // code
  }

Example 1:

  public class MultipleCatchExample1 {
    public static void main(String[] args) {
      try {
        int numbers[] = { 10, 20, 30, 40, 50 };
        System.out.println("Accessing array element beyound range: " + numbers[10]);
      } catch (ArithmeticException e) {
        System.out.println("Error: ArithmeticException");
      } catch (ArrayIndexOutOfBoundsException e) {
        System.out.println("Error: ArrayIndexOutOfBoundsException");
      } catch (Exception e) {
        System.out.println("Error: Exception - Other exception");
      }
      System.out.println("Out of try-catch block...");
    }
  }

Output

Error: ArrayIndexOutOfBoundsException
Out of try-catch block...

Example 2:

  public class MultipleCatchExample2 {
    public static void main(String[] args) {
      try {
        int num1 = 50;
        int num2 = 0;
        System.out.println("Dividing Numbers: " + num1 / num2);
      } catch (ArithmeticException e) {
        System.out.println("Error: ArithmeticException");
      } catch (ArrayIndexOutOfBoundsException e) {
        System.out.println("Error: ArrayIndexOutOfBoundsException");
      } catch (Exception e) {
        System.out.println("Error: Exception - Other exception");
      }
      System.out.println("Out of try-catch block...");
    }
  }

Output

Error: ArithmeticException
Out of try-catch block...

Example 3:

  public class MultipleCatchExample3 {
    public static void main(String[] args) {
      try {
        String str = "Some Text Data";
        System.out.println("Length: " + str.length());
        str = null;
        System.out.println("Length: " + str.length());
      } catch (NullPointerException | NumberFormatException e) {
        System.out.println("Error: Exception occured...");
      }
    }
  }

Output

Length: 14
Error: Exception occured...

Example 4:

  public class MultipleCatchExample4 {
    public static void main(String[] args) {
      try {
        int numbers[] = { 10, 20, 30, 40, 50 };
        System.out.println("Accessing array element beyound range: " + numbers[10]);
      } catch (ArithmeticException | ArrayIndexOutOfBoundsException e) {
        System.out.println("Error: Exception occured...");
      }
      System.out.println("Out of try-catch block...");
    }
  }

Output

Error: Exception occured...
Out of try-catch block...
