Question

type the programs output
public class arrayoutput {
public static void main (string args) {
final int num_elements = 3;
int uservals = new intnum_elements;
int i;

uservals0 = 3;
uservals1 = 4;
uservals2 = 9;

uservals0 = uservals2;
uservals2 = uservals1;

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

Explanation:

Step1: Analyze array initialization

The array userVals is initialized with 3 elements. Initially, userVals[0] = 3, userVals[1] = 4, userVals[2] = 9.

Step2: Update array elements

Then, userVals[0] = userVals[2] (so userVals[0] becomes 9), and userVals[2] = userVals[1] (so userVals[2] becomes 4).

Step3: Iterate and print

The for loop iterates from i = 0 to i < userVals.length (i.e., 0, 1, 2). For each i, it prints userVals[i].
