Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

In Java please explain how this code prints negative elements as positive

public class arrayOutput {
public static void main (String [] args) {
final int NUM ELEMENTS = 4;
}
}
int [] userVals = new int [NUM_ELEMENTS];
int i;
userVals [0] = -2;
userVals [1]
userVals [2]
userVals [3] =
=
}
=
}
=
for (i = 0; i < userVals.length; ++i) {
if (userVals[i] < 0) {
userVals[i] = -1 * userVals[i];
System.out.println (userVals[i]);
4;
- 6;
8;
