int oldest = ages[0];
for (int i = 1; i < ages.length; i++) {
youngest = Math.min(youngest, ages[i]);
oldest = Math.max(oldest, ages[i]);
}
```

In this example, the `youngest`

variable is initialized to the first age in the array, and the `oldest`

variable is also initialized to the same value. The loop then iterates through the remaining ages, updating the `youngest`

and `oldest`

variables accordingly.

try {

int result = 5 / 0; // Division by zero, an ArithmeticException will be thrown

} catch (ArithmeticException e) {

System.out.println(“Error: Division by zero is not allowed.”);

// Handle the exception gracefully, log the error, or perform any necessary actions

}

“`

By enclosing the potentially problematic code within a try-catch block, you can catch and handle the specific exception that occurs. In this case, we catch the ArithmeticException and display an error message informing the user that division by zero is not allowed.

### Invalid Input Handling

Another crucial aspect of **error handling** is dealing with **invalid input**. It is important to validate the input data before performing any calculations to avoid unexpected results or errors. The following example illustrates how to handle **invalid input** when calculating the square root using the Java Math class:
