Question

Double any element's value that is less than minValue. Ex: If minValue = 10, then dataPoints = {2, 12, 9, 20} becomes {4, 12, 18, 20}.
import java.util.Scanner;
public class StudentScores {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
final int NUM_Points = 4;
int[] dataPoints = new int[NUM_POINTS];
int minValue;
int i;
minValue = scnr.nextInt();
for (i = 0; i < dataPoints.length; ++i) {
dataPoints[i] = scnr.nextInt();
}
/* Your solution goes here */
for (i = 0; i < dataPoints.length; ++i) {
System.out.print(dataPoints[i] + " ");
}
System.out.println();
}
}

Answer 1

Answer:

Following are the code to this question:

for(i=0;i<dataPoints.length;++i) //define loop to count array element  

{

if(dataPoints[i]<minValue) // define condition that checks array element is less then minValue

{

dataPoints[i] = dataPoints[i]*2; //double the value

}

}

Explanation:

Description of the code as follows:

• In the given code, a for loop is declared, that uses a variable "i", which counts all array element, that is input by the user.
• Inside the loop and if block statement is used, that check array element value is less then "minValue", if this condition is true.  
• So, inside the loop, we multiply the value by 2.
