Write a program that reads a collection of positive and nega

Write a program that reads a collection of positive and negative numbers and multiplies only the positive integers. Loop exit should occur when three consecutive negative values are read.

Solution

package org.students;

import java.util.Scanner;

public class MultiplyPositiveNos {

   public static void main(String[] args) {
       //Declaring variables
       int number,result=1,count=0;
      
       //Scanner class Object is used to read the inputs entered by the user
       Scanner sc=new Scanner(System.in);
      
       /* This loop continues to executes until the user
       * enters consecutively 3 times negative number
       */
       while(true)
       {
          
       //Getting the Integer entered by the user
       System.out.print(\"\ Enter a number (Positive /Negative) :\");
       number=sc.nextInt();
      
       /* Checking whether the entered number is positive or not
       * if yes,Then it performs multiplication.
       * and set count variable to zero
       * If not,Incrementing the count variable by 1
       */
if(number>0)
       {
//Performing multiplication
       result*=number;
      
       //Setting count variable to zero
       count=0;
       }
       else
       count++;  
  
/* Checking if the count value is 3
* If yes,Then this while loop will get break
* and control will comes out of the loop
*/
if(count==3)
break;
       }
      
      
       //Displaying the final Result after multiplying alla positive numbers
       System.out.println(\"The Multiplicatin of Positive Integers is :\"+result);
   }

}

Output:

Enter a number (Positive /Negative) :5

Enter a number (Positive /Negative) :-2

Enter a number (Positive /Negative) :3

Enter a number (Positive /Negative) :-1

Enter a number (Positive /Negative) :-2

Enter a number (Positive /Negative) :2

Enter a number (Positive /Negative) :1

Enter a number (Positive /Negative) :-1

Enter a number (Positive /Negative) :-2

Enter a number (Positive /Negative) :-3
The Multiplicatin of Positive Integers is :30
