o Returns the array
 
? Include a static method that:

Hi Friend,

Try the following code:

import java.util.*;
public class ArrayExamples{

public static int[] readIntegers(){
int arr[]=new int[5];
Scanner input=new Scanner(System.in);
System.out.println("Enter numbers: ");
for(int i=0;i<arr.length;i++){
arr[i]=input.nextInt();
}
return arr;
}
public static int largestNo(int arr[]){
int max=arr[0];
for (int i=1; i<arr.length; i++) {
if (arr[i] > max) {
max = arr[i];
}
}
return max;
}
public static int smallestNo(int arr[]){
int min=arr[0];
for (int i=1; i<arr.length; i++) {
if (arr[i]< min) {
min = arr[i];
}
}
return min;
}
public static void main(String[]args){
int arr[]=ArrayExamples.readIntegers();
int largest=ArrayExamples.largestNo(arr);
int smallest=ArrayExamples.smallestNo(arr);
System.out.println("Largest No: "+largest);
System.out.println("Smallest No: "+smallest);
}
}

Thanks
