Tugas IV

Mencari nilai rata-rata,nilai tertinggi dan nilai terendah dengan menggunakan program java

import java.io.*;
public class rata{
 public static void main(String Arg[])throws IOException{
 int Nilai[];
 Nilai=new int[20];
 double rata=0,total=0;
 int nmax=0;int nmin=1000;
 String str;
 int i,jdata;

 BufferedReader Get=new BufferedReader(new InputStreamReader(System.in));

 System.out.println("menghitung Nilai");
 System.out.print("jumlah data:");str=Get.readLine();
 jdata=Integer.parseInt(str);
 for(i=0;i<jdata;i++){
 System.out.print("Nilai ke:"+(i+1)+":");
 str=Get.readLine();
 Nilai[i]=Integer.parseInt(str);
 }
 rata=0;total=0;

 for(i=0;i<jdata;i++){
 System.out.println("Nilai ke:"+(i+1)+":"+Nilai[i]);
 total=total+Nilai[i];
 if(Nilai[i]>nmax)nmax=Nilai[i];
 if(Nilai[i]<nmin)nmin=Nilai[i];
 }
 rata=total/jdata;
 System.out.println("Nilai rata-rata:"+rata);
 System.out.println("Nilai tertinggi:"+nmax);
 System.out.println("Nilai terendah:"+nmin);
    }
