There is an application which inputs hundred numbers from the user, if user enters a positive number it increments valid numbers count. But if a user enters other than integer it terminates. You are required to make changes in given code such that instead of termination it shows message “input is not valid” and re input a number. importjavax. swing.*; publicclass QuestionNumber4 { publicstaticvoidmain(String[] args) { intcountValidNumber=0; int num; for(inti=0;i 0){ countValidNumber++; } } System. out. println("Valid Numbers Are:"+countValidNumber); }

Following are the correct code to this question:

import java.util.*;//import package

public class QuestionNumber4 //defining class  QuestionNumber4

{

   public static void main(String[] args)//defining the main method

   {

       int countValidNumber=0,n=0;//defining integer varaible

       int num[]= new int[100]; //defining integer array num

       Scanner ob=new Scanner(System.in);//creating Scanner class Object

       try //using try block

       {

       for(int i=0;i<100;i++)//defining loop to input 100 values

       {num[i]=ob.nextInt();//input value in array

        n=n+num[i];//add number

        countValidNumber++;//count input value

       if(n<0){}}//defining if block to check another value

       }

       catch(Exception e) //catch block to handle Exception

       {

       System.out.println("input is not valid");// print message    

       }

   System.out.println("total intered number are: " + countValidNumber);//print times of input value  

   }  

}

Output:

2

5

7

9

o

input is not valid

total intered nyumber are: 4

Explanation:

following are the description of the above code:

answer; (c) series 3; i believe this is the correct answer. good luck
