EXERCISE 107 : Use multiple try – catch blocks

Objectives

At the end of this exercise you shall be able to
• develop Java programs using multiple try – catch blocks.

Requirements

Tools/Materials

• PC / laptop with windows OS
• SDK software
• Test editor (Visual studio/ subline/ notepad)

Procedure

// programs using multiple try – catch blocks
public class MultipleTryCatchExample {
public static void main(String[] args) {
try {
// First try block
int[] numbers = {1, 2, 3};
System.out.println(“Element at index 5: “ + numbers[5]); // This will throw ArrayIndexOutOfBoundsException
} catch (ArrayIndexOutOfBoundsException e) {
System.out.println(“Caught ArrayIndexOutOfBoundsException: “ + e.getMessage());
}

try {
// Second try block
String str = null;
System.out.println(“Length of the string: “ + str.length()); // This will throw NullPointerException
} catch (NullPointerException e) {
System.out.println(“Caught NullPointerException: “ + e.getMessage());
}

try {
// Third try block
int result = 10 / 0; // This will throw ArithmeticException
System.out.println(“Result of division: “ + result);
} catch (ArithmeticException e) {
System.out.println(“Caught ArithmeticException: “ + e.getMessage());
}
}
}
