Question

public class arrayoutput {
public static void main (string args) {
final int num_elements = 4;
int uservals = new intnum_elements;
int i;

uservals0 = -1;
uservals1 = 4;
uservals2 = -6;
uservals3 = 7;

for (i = 0; i < uservals.length; ++i) {
if (uservalsi < 0) {
uservalsi = -1 * uservalsi;
}
system.out.println(uservalsi);
}
}
}

Explanation:

Step1: Analyze the array initialization

The array userVals is initialized with values [-1, 4, -6, 7].

Step2: Iterate through the array

The for loop iterates from i = 0 to i = 3 (since userVals.length = 4).

• When i = 0: userVals[0]=-1 < 0, so userVals[0]=-1*(-1) = 1. Then print 1.
• When i = 1: userVals[1]=4 >= 0, no change. Print 4.
• When i = 2: userVals[2]=-6 < 0, so userVals[2]=-1*(-6) = 6. Print 6.
• When i = 3: userVals[3]=7 >= 0, no change. Print 7.
