In this problem, you will create a program that wraps string-to-integer conversion in a try-catch statement and displays an error message when a NumberFormatException occurs.

try-catch Statement Basics

The try-catch statement is a mechanism for safely executing code that may throw errors.

Basic Syntax

try {
  // Code that may throw an exception
} catch (ExceptionType variableName) {
  // Error handling code
}

Learning Points

• NumberFormatException occurs when number conversion fails
• try-catch prevents program crashes
• Proper exception handling makes programs user-friendly
