Java Program to handle multiple exception in a single catch .

Objective

Write a Java program to handle multiple exceptions in a single catch block (Multi-catch).

Algorithm / Approach

  1. Use the same risky division and array access method.
  2. Wrap the method call in a try block.
  3. Write a single catch block using the pipe operator: catch (ArithmeticException | ArrayIndexOutOfBoundsException e).
  4. Inside the catch block, print the exception object e to see exactly which error was triggered.
Test.java 
import java.util.Scanner;
class Test {
 public int find(int x, int y) {
  int[] a = {1,2,3,4,5};
  int z = x/y;
  //May throw ArithmeticException
  return a[z];
//may throw ArrayIndexOutOfBoundsExcep.
 }
}
class Main {
 public static void main(String[] a)
 {
  Scanner s=new Scanner(System.in);
  System.out.print("Enter Num1: ");
  int x = s.nextInt();
  System.out.print("Enter Num2: ");
  int y = s.nextInt();
  Test t = new Test();
  try { 
   int res = t.find(x,y);
   System.out.println("Result = "+res);
  }
  catch(ArithmeticException |
    ArrayIndexOutOfBoundsException e){
   System.out.println(e);
  }
 }
}

Expected Output

Enter Num1: 20
Enter Num2: 2
java.lang.ArrayIndexOutOfBoundsException: 10

Explanation of the Program

  • Before Java 7, if you wanted to handle two different exceptions with the exact same error-handling logic, you had to duplicate the code across two catch blocks.
  • The Multi-catch feature allows you to catch multiple distinct exception types in a single block using the bitwise OR (pipe) operator |.
  • This significantly reduces code duplication while maintaining strict, specific exception checking (unlike catching the general Exception superclass).
