Question

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

uservals0 = 2;
uservals1 = 6;
uservals2 = 7;
uservals3 = 4;

maxval = uservals0;
for (i = 0; i < uservals.length; ++i) {
if (uservalsi >= maxval) {
maxval = uservalsi;
system.out.println(maxval);
}
}
}
}

Explanation:

Step1: Initialize variables

The array userVals is initialized with values [2, 6, 7, 4]. maxVal is initially set to userVals[0] (which is 2).

Step2: First iteration (i = 0)

Since userVals[0] = 2 and maxVal = 2, the condition userVals[i] >= maxVal is true. So, maxVal remains 2 and 2 is printed.

Step3: Second iteration (i = 1)

userVals[1] = 6 and 6 >= 2 is true. Now maxVal = 6 and 6 is printed.

Step4: Third iteration (i = 2)

userVals[2] = 7 and 7 >= 6 is true. Now maxVal = 7 and 7 is printed.

Step5: Fourth iteration (i = 3)

userVals[3] = 4 and 4 >= 7 is false. So, no change in maxVal.

Answer:

2
6
7
