Tugas Pemprograman berbasis Objek

1.       Program matrik

Codding :

package matrik2dimensi;

import javax.swing.*;

public class ContohArray2DimensiPerkalian {

public static void main (String[] args) {

 int A [][] = new int [3][3];

int B [][] = new int [3][3];

int hasil[][]=new int [3][3];

String  dataA [][] = new String [3][3];

//String  dataA [][] = new String [3][3];

String dataB [][] =new String[3][3];

String hasilS [][] = new String [3][3];

int i,j,k,m;

i=0;

j=0;

k=0;

m=0;

 //  *MATRIKS A *//

do {

j=0;

do {

dataA[i][j]=  JOptionPane.showInputDialog(" Masukan data A [" + i + "]["+ j + "]" );

A[i][j]= Integer.parseInt(dataA[i][j]);

 j++;

}

while (j<3); //end do j

i++;

}

while(i<3);   // end do i

//    * MATRIKS B *

 k=0;

do {

m=0;

do {

dataB[k][m]=  JOptionPane.showInputDialog(" Masukan data B [" + k + "]["+ m + "]" );

B[k][m]= Integer.parseInt(dataB[k][m]);

m++;

}

while (m<3); //end do j

k++;

}

while(k<3);   // end do i

//   *  Menampilkan data pada Matriks A *

for (k=0; k<3; k++ ) // for pada  ini untuk menampilkan data {

for (m=0; m<3; m++ ) {

System.out.print("  "+A[k][m]); // Menampilkan data A [i][j]

}

System.out.println();   // memubuat baris ke bawah

System.out.println("\n\n");

//   * Menampilkan data pada Matriks B *

for (k=0; k<3; k++ ) // for pada  ini untuk menampilkan data {

for (m=0; m<3; m++ ) {

System.out.print("  "+B[k][m]); // Menampilkan data B [k][m]

}

System.out.println();   // memubuat baris ke bawah

// *  UNTUK MENGALIKAN KEDUA MATRIKS DI ATAS  *

for (i=0; i<3; i++) {

for (j=0; j<3; j++) {

hasil[i][j] = 0;

for (k=0; k<3;  k++) {

hasil[i][j] += A[i][k] * B[k][j];

}

}

}

System.out.println("\n\n");

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

System.out.println("\n");

// * UNTUK MENAMPILKAN HASIL*

for(i=0; i<3; i++) {

for(j=0; j<3; j++) {

//System.out.println("hasil tambah adalah:");

System.out.print(" "+ hasil[i][j]);

}

System.out.println(" ");

}

System.out.println();   // memubuat baris ke bawah

}

}

2.      Program Pemecahan Nilai Mata Uang

Berikut Codingnya :

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

public class uang {

public static void main(String[] args){

int data = 0;

System.out.println("Silahkan masukan nilai uang anda: ");

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

String angkaInput = null;

try{

angkaInput = bfr.readLine();

}

catch(IOException e){

e.printStackTrace();

}

int Data = Integer.valueOf(angkaInput).intValue();

if((Data>100000)){

data = Data/100000;

System.out.println("jumlah uang seratus ribuan :"+data);

}

if(Data>50000){

System.out.println("jumlah uang seribuan :"+data);

}
