Feedback? CHALLENGE ACTIVITY 5.2.2: Printing array elements. Write three statements to print the first three elements of array run Times. Follow each statement with a newline. Ex: If runTime = (800,775, 790, 805, 808) print: 800 775 790 Note: These activities will test the code with different test values. This activity will perform two tests, both with a 5 element array. See 'How to Use zyBooks". Also note: If the submitted code tries to access an invalid array element, such as run Times(9) for a 5-element array, the test may generate strange results. Or the test may crash and report Program end never reached", in which case the system doesn't print the test case that caused the reported message. import java.util.Scanner; public class Print Run Times public static void main(String[] args) { Scanner scnr = new Scanner(System.in); final int NUM_ELEMENTS - 5; int [] runTimes = new int [NUM ELEMENTS); int i; D!! for (i = 0; i < runTimes.length; ++i) { runTimes [1] - scnr.nextInt(); } /* Your solution goes here } 1 Run

Solution :

import java.util.Scanner;
// class PrintRunTimes
public class PrintRunTimes
{
// main function
public static void main(String[] args)
{
// create an object of scanner class
Scanner scnr = new Scanner(System.in);
// initialize the NUM_ELEMENTS = 5
final int NUM_ELEMENTS = 5;
// delclare an array
int [] runTimes = new int[NUM_ELEMENTS];
// declare an integer i
int i;
// input array elements
for(i=0;i<runTimes.length;++i)
{
runTimes[i]=scnr.nextInt();
}
// print the first three elements of array runTimes using three println statements
System.out.println(runTimes[0]);
System.out.println(runTimes[1]);
System.out.println(runTimes[2]);
}
}
