Contoh Program Membuat Nilai Rata Rata Menggunakan Java

==========================

import java.util.Scanner;

import java.io.*;

public class Nilai_Rata2 {

public static void main (String [] eee) {

Scanner M = new Scanner (System.in);

int N,x,i,tot=0;

float rata2;

long NPM;

System.out.print("Masukan Nama Mahasiswa = ");

try {

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

String mhsw = nama.readLine();

} catch (IOException e) {

System.out.println("ERROR");

}

System.out.print("Masukan NPM = ");

NPM = M.nextLong();

System.out.println();

System.out.print("Masukan Jumlah Mata Kuliah = ");

N = M.nextInt();

for (i=1; i<=N; i++) {

System.out.print("Masukan Nilai Mata Kuliah ke-"+i+" = ");

x = M.nextInt ();

tot = tot + x;

}

System.out.println("=========================================");

rata2 = tot /N ;

System.out.println("Nilai Rata-Rata Mata Kuliah = "+rata2);

if (rata2>=90) { System.out.println("GRADE A"); }

else if (rata2>=80 && rata2<=89) { System.out.println("GRADE B"); }

else if (rata2>=70 && rata2<=79) { System.out.println("GRADE C"); }

else if (rata2>=60 && rata2<=69) { System.out.println("GRADE D"); }

else { System.out.println("GRADE E"); }

}

}
