Mencari Nilai Rata-Rata

import java.util.Scanner;







class nilai_rata2{


public static void main (String[]args){


Scanner s=new Scanner(System.in);






String nama,npm;


int nilai_MK,jumlah=0,jumlah_MK,i;


double nilai_rata2;


System.out.print("Nama Mahasiswa: ");nama=s.nextLine();


System.out.print("NPM: ");npm=s.nextLine();


System.out.print("Jumlah_MK: ");jumlah_MK=s.nextInt();






for (i=1;i<=jumlah_MK;i++)


{


System.out.print("nilai MK ke-"+i+" = ");nilai_MK=s.nextInt();


jumlah=jumlah+nilai_MK;


}


nilai_rata2=jumlah/jumlah_MK;


System.out.println("Nilai rata rata ="+""+nilai_rata2);


}


}


Mencari Harga Disc dan Bonus


import java.util.Scanner;



class diskon_pembelian {


public static void main (String [] args) {


Scanner s=new Scanner (System.in) ;






int i,harga, n;


double jumlah,total=0 ;


String nama;






System.out.print("Nama Costomer :");nama=s.nextLine ();


System.out.print("Jumlah Barang :");n=s.nextInt ()






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


System.out.print("Harga Barang ke-"+i+" : Rp, ");harga=s.nextInt ();


total=total+harga ;}


System.out.println("Total : "+total);






if(total>500000)


System.out.print("Total setelah diskon : Rp "+(jumlah =(total-(total * 0.05))));


else if(total>7500000)


System.out.print("Total setelah diskon : Rp "+(jumlah= (total-(total * 0.1))));


else


System.out.print("Total setelah diskon : Rp "+(jumlah= (total-(total * 0.15))));






System.out.println();






if(jumlah>900000)


System.out.println("Bonus : Kompor gas");


else if(jumlah>700000)


System.out.println("Bonus : DVD player");
