Question
Simple try-catch-finally Program
This lab is a simple program that demonstrates how try-catch-finally works. You will
notice the output when you enter incorrect input (for example, enter an incorrect index or an
alpha character instead of an integer). Type up the code, execute and submit the results ONLY.
1. Enter a valid array index
2. Enter an invalid array index
3. Enter a letter instead of an integer - NOTE: Using the general error will show you the
type of exception was caught, and you can then update your code to catch that type of
error.
4. Try putting the "Exception e" before the IndexOutOfBounds Exception eob what happens
and are you able to run the code - what happens?
CODE:
import java.util.Scanner;
public class TryCatchFinally {
public static void main(String[] args) {
// Instantiate a scanner
Scanner input = new Scanner(System.in);
}
}
// Create an array with 4 values
int an IntArr[] = {10, 15, 26, 99);
try
{
System.out.println("Enter the index to see the number: ");
int ind input.nextInt ();
System.out.println("The value in the "+ind + " index is: " + anIntArr[ind]);
}
catch (IndexOutOfBounds Exception eob)
{
}
System.out.println("IndexOutOfBounds Exception Error: + eob + "\n");
catch (Exception e)
{
}
System.out.println("GeneralException Error: " + e+ "\n");
finally {
input.close();
System.out.println("finally block executed");
}
// rest program will not execute
System.out.println("Outside try-catch-finally clause\nProgram finished");
