Simple try-catch Program
This lab is a simple program that demonstrates how try-catch works. You will notice the output when you enter incorrect
input (for example, enter a string or double instead of an integer). Type up the code, execute and submit the results ONLY. Do at
least 2 valid inputs and 1 invalid. NOTE: The program does not stop executing after it encounters an error!
CODE:
import java.util.Scanner;
public class TryCatch Example Simple {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int num = 0;
System.out.println("Even number tester.\n");
System.out.println("Enter your name: ");
String name = input.nextLine();
while (true)
{
try {
System.out.println("Enter an integer : ");
// DebugFive2.java
// Decides if two numbers are evenly divisible
import java.util.Scanner;
public class DebugFive2
{
publicstaticvoidmain(Stringargs[])
{
int num;
int num2;
Scanner input =newScanner(System.in);
System.out.print("Enter a number ");
num = input.nextInteger()
System.out.print("Enter another number ");
num2 = inputnextInt();
if((num % num2 ==0) && (num2 % num) ==0)
System.out.println("One of these numbers is evenly divisible into the other");
else
System.out.println("Neither of these numbers is evenly divisible into the other");
}
}
The following code is in Java:
// Assume inputFile references a Scanner object.
try
{
input = inputFile.nextInt();
}
finally
{
inputFile.close();
}
catch (InputMismatchException e)
{
System.out.println(e.getMessage());
}
1)What is the issue with this code?2) How can it be fixed?
