Tugas 4

Latihan Input Scanner & Konversi

1. Listing Program “Nilai” dengan Inputan Scanner

import java.util.Scanner;

class nilai1

{

                public static void main(String args[])

                {

                                Scanner input = new Scanner (System.in);

                                String nama;

                                double n1,n2,n3,UTS,UAS,Tugas,Akhir;

                System.out.print("Masukkan Nama Siswa : ");

                                nama = input.nextLine();

                System.out.print("Nilai UTS : ");

                                n1 = input.nextDouble();

                System.out.print("Nilai UAS : ");

                                n2 = input.nextDouble();

                System.out.print("Nilai Tugas Mandiri : ");

                                n3 = input.nextDouble();

                                UTS = 0.35 * n1;

                                UAS = 0.45 * n2;

                                Tugas = 0.2 * n3;

                System.out.println("\nNillai UTS Murni : "+UTS);

                System.out.println("\nNillai UAS Murni : "+UAS);

                System.out.println("\nNillai Tugas Mandiri Murni : "+Tugas);

                                Akhir = ((UTS + UAS) + Tugas);

                System.out.println("\nNillai Akhir yang diperoleh yaitu : "+Akhir);

                }

}

2. Listing Program “Nilai” dengan Cara Konversi

import java.io.*;

class nilai2

{

                public static void main(String args[]) throws Exception

                {

                                InputStreamReader masukan = new InputStreamReader(System.in);

                                BufferedReader input = new BufferedReader(masukan);

                                String nama;

                                String s1,s2,s3;

                                double n1,n2,n3,UTS,UAS,Tugas,Akhir;

                System.out.print("Masukkan Nama Siswa : ");

                                nama = input.readLine();

                System.out.print("Masukkan Nilai UTS : ");

                                s1 = input.readLine();

                System.out.print("Masukkan Nilai UAS : ");

                                s2 = input.readLine();

                System.out.print("Masukkan Nilai Tugas Mandiri : ");

                                s3 = input.readLine();

                                n1 = Double.parseDouble(s1);

                                n2 = Double.parseDouble(s2);

                                n3 = Double.parseDouble(s3);

                                UTS = 0.35 * n1;

                                UAS = 0.45 * n2;

                                Tugas = 0.2 * n3;

                System.out.println("\nNilai UTS Murni : "+UTS);

                System.out.println("\nNilai UAS Murni : "+UAS);

                System.out.println("\nNilai Tugas Mandiri Murni : "+Tugas);

                                Akhir = ((UTS + UAS) + Tugas);

                System.out.println("\nNilai Akhir yang diperoleh yaitu : "+Akhir);

                }
