Question

Class Main {

Answer 1

See below for the modified program in Java

How to modify the program?

The for loop statements in the program are:

• for (int i = 0; i < arr.length; i++) { arr[i] = rd.nextInt(1000); }
• for (int i = 0; i < arr.length; i++) { System.out.println(arr[i]); }

To use the enhanced for loop, we make use of the for each statement.

This syntax of the enhanced for loop is:

for(int elem : elems)

Where elem is an integer variable and elems is an array or arrayList

So, we have the following modifications:

• i = 0; for (int num : arr){ arr[i] = rd.nextInt(1000); i++;}
• for (int num : arr) { System.out.println(num); }

Hence, the modified program in Java is:

class Main {

static int[] createRandomArray(int nrElements) {

Random rd = new Random();

int[] arr = new int[nrElements];

int i = 0;

for (int num : arr){

arr[i] = rd.nextInt(1000);

i++;

}

return arr;

}

static void printArray(int[] arr) {

for (int num : arr) {

System.out.println(num);

}

}

}

public static void main(String[] args) {

int[] arr = createRandomArray(5);

printArray(arr);

}

}
