Java Array Example

import java.util.*;
class  ArrayExample6{
    public static int getMaxValue(int[] arr){
  int maxValue = arr[0];
  for(int i=1;i < arr.length;i++){
    if(arr[i] > maxValue){
      maxValue = arr[i];
    }
  }
  return maxValue;
}

public static int getMinValue(int[] arr){
  int minValue = arr[0];
  for(int i=1;i<arr.length;i++){
    if(arr[i] < minValue){
      minValue = arr[i];
    }
  }
  return minValue;
}
    public static void main(String[] args) 
    {
        int sum=0;

        Scanner input=new Scanner(System.in);
        System.out.println("Enter Array Elements: ");
        int array[]=new int[10];
        for(int i=0;i<array.length;i++){
            int num=input.nextInt();
            if(num<0||num>100){
                System.out.print("Not in a range(0-100)!Re-enter number: ");
                num=input.nextInt();
            }
            array[i]=num;
            sum+=array[i];

        }
        System.out.println("Sum Of Array Elements is: "+sum);
        System.out.println("Mean of Array Elements is: "+sum/array.length);
        System.out.println("Smallest No: "+getMinValue(array));
        System.out.println("Largest No: "+getMaxValue(array));
    }
}
