Sum, Average, Max., Min of Elements in an Array

Code:

import java.io.*;
import java.lang.*;
import java.util.Scanner;
class arra
{
    public static void main(String args[])throws IOException
    {
    int sum=0,avg,max,mini,n,i;
    Scanner in=new Scanner(System.in);
    System.out.println("enter three  number");
    n=in.nextInt();
    int[] h= new int[n];
     System.out.println("enter the value");
     for(i=0;i<n;i++)
     {
         h[i]=in.nextInt();
     }
     for(i=0;i<n;i++)
     {
         sum=sum+h[i];
     }
     System.out.println("sum of the array"+sum);
     avg=sum/n;
     System.out.println("sum of the average"+avg);
     max=h[0];
     mini=h[0];
     for(i=0;i<n;i++)
     {
         if(h[i]>max)
         {
             max=h[i];
         }
         else if(h[i]<mini)
             {
             mini=h[i];
         }
     }
     System.out.println("maximum value"+max);
     System.out.println("minimum  value"+mini);
    }
    }
