Write a program that prompts the user to enter a series of integers from the command line (-1 to stop). Use Java's Exception handling to ignore invalid input.

Thank You

Hi Friend,

Try the following code:

import java.util.*;
public class ExceptionHandling
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
System.out.println("Enter Integer values: ");
int num=0;
while(num!=-1){
try
{
num = input.nextInt();
}
catch(Exception e){
input.skip("\\w+");
}
}
}
}

Thanks
