Array satu dimensi dan dua dimensi

public class Array1Dimensi {

    public  static void main(String[] args){
        int bab[] = new int[10];

        for(int i=0;i<10;i++){
            bab[i]=i+1;
        }

        for(int i=0;i<10;i++){
            System.out.println("array ke-"+i+" = "+bab[i]);
        }

Array Mahasiswa

public class ArrayMahasiswa {
 
    public static void main(String[] args){
        int loop=Integer.parseInt(JOptionPane.showInputDialog("Berapa Jumlah data ?"));
        String[] npm = new String[loop];
        String[] nama = new String[loop];
        String[] alamat = new String[loop];
        for(int i=0;i<loop;i++){

Programing with Java2 (perhitungan pada Matrix)

public class Matrixx {
    public static void main(String[]args){

        int BarisMatrix1 = Integer.parseInt(JOptionPane.showInputDialog("Matrix 1\nJumlah Baris"));
        int KolomMatrix1 = Integer.parseInt(JOptionPane.showInputDialog("Matrix 1\nJumlah Kolom"));

        int BarisMatrix2 = Integer.parseInt(JOptionPane.showInputDialog("Matrix 2\nJumlah Baris"));

Java - Array Dua Dimensi

contoh 1:
public static void main(String[] args){
        int[][] arr = {{5,23,3},{6,72,9}};
        System.out.println("arr[1][2] + arr[0][0] = "+(arr[1][2] + arr[0][0]));
        System.out.println("arr[1][1] - arr[0][1] = "+(arr[1][1] - arr[0][1]));
        System.out.println("arr[1][1] / arr[0][2] = "+(arr[1][1] / arr[0][2]));
        System.out.println("arr[1][2] * arr[1][0] = "+(arr[1][2] * arr[1][0]));

Java - Array satu dimensi

public static void main(String[]args){

        double[] angka = new double[3];

        angka[0] = Double.parseDouble(JOptionPane.showInputDialog("input angka ke 1"));;
        angka[1] = Double.parseDouble(JOptionPane.showInputDialog("input angka ke 2"));;
        angka[2] = 0;

        System.out.println("angka ke 1 = "+(angka[0]));
