Question

A function defined beginning with void SetNegativesToZeros(int userValues[], ... should modify userValues such that any negative integers are replaced by zeros. The function _____.

Answer 1

Answer:

   public static void setNegativesToZero(int userValues[]){

       System.out.println("Array before setting negatives to zero "+Arrays.toString(userValues));

       for(int i=0; i<userValues.length; i++){

           if(userValues[i]< 1){

               userValues[i] = 0;

           }

       }

       System.out.println();

       System.out.println("Array After setting negatives to zero "+Arrays.toString(userValues));

   }

Explanation:

Using Java programming Language, the method is created to receive an array of ints as parameter (as specified in the question)

Using a for loop, we iterate over the entire array checking for values that are negative (<0) and setting them to zero.

See a complete program below

import java.util.Arrays;

import java.util.Scanner;

public class num1 {

   public static void main(String[] args) {

   // Create an array and assign values

       int [] arr = {1,2,3,-1,1,2,-4};

   //Calling the method setNegativesToZero

   setNegativesToZero(arr);

   }

//Creating the Method

   public static void setNegativesToZero(int userValues[]){

       System.out.println("Array before setting negatives to zero "+Arrays.toString(userValues));

       for(int i=0; i<userValues.length; i++){

           if(userValues[i]< 1){

               userValues[i] = 0;

           }

       }

       System.out.println();

       System.out.println("Array After setting negatives to zero "+Arrays.toString(userValues));

   }
