Question
JAVA:::Write a loop that subtracts 1 from each element in lowerScores. If the element was already 0 or negative, assign 0 to the element. Ex: lowerScores = {5, 0, 2, -3} becomes {4, 0, 1, 0}.
CODE:
public class StudentScores {
public static void main (String [] args) {
final int SCORES_SIZE = 4;
int[] lowerScores = new int[SCORES_SIZE];
int i = 0;
lowerScores[0] = 5;
lowerScores[1] = 0;
lowerScores[2] = 2;
lowerScores[3] = -3;
/* Your solution goes here */
for (i = 0; i < SCORES_SIZE; ++i) {
System.out.print(lowerScores[i] + " ");
}
System.out.println();
return;
}
}
Explanation / Answer
StudentScores.java
public class StudentScores {
public static void main(String[] args) {
final int SCORES_SIZE = 4;
int[] lowerScores = new int[SCORES_SIZE];
lowerScores[0] = 5;
lowerScores[1] = 0;
lowerScores[2] = 2;
lowerScores[3] = -3;
/* This loop will reduce 1 from the element from the array
* if the element is greater than 0 else make that element 0
*/
for (int i = 0; i < lowerScores.length; i++) {
if (lowerScores[i] > 0) {
lowerScores[i] = lowerScores[i] - 1;
}
else {
lowerScores[i] = 0;
}
}
//Displaying the elements
for (int i = 0; i < SCORES_SIZE; ++i) {
System.out.print(lowerScores[i] + " ");
}
System.out.println();
return;
}
}
