Mengubah Ukuran Array

Menghapus elemen array

import javax.swing.JOptionPane;
public class HapusArray {


ring[] args) {

 int[] data = new int[5];
 public static void main(S
t

 for(int index=0; index < data.length; index++) {


 data[index] = (int) (Math.random()*100)+20;
 

}


System.out.println("Data awal");


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




 for(int index=0; index < data.le
ngth; index++) {

ln("data" + "[" + index + "]" + data[index]);
 }

 int cari = 
System.out.prin
tInteger.parseInt(JOptionPane.showInputDialog(null, "Data yang dihapus:"));

 if(data[index] == cari)
boolean ketemu = false;

 for(int index=0; index < data.length; index++) {
{
 ketemu = true;

= 0;
 f
break;
 }
 }

 if (ketemu == true) {
 int[] temporary = new int[data.length-1];
 int counter
 or(int i=0; i<temporary.length; i++) {
 if(data[i] == cari) {
 counter++;

[counter];
 counter++;
 }
 }


temporary[i] = data[counter];
 counter++;
 }
 else
 {
 temporary[i] = dat
a data = new int[temporary.length];
 System.out.println("");

println("------------------------");

 for(int i
System.out.println("setelah penghapusan data");
 System.out
.=0; i<data.length; i++) {
 data[i] = temporary[i];
 System.out.println("data" + "[" + i + "]" + data[i]);
 }


} else {
 JOptionPane.showMessageDialog(null, "tidak ada");
 }

 }


}

output program:

Data awal
---------


data[1]66
data[0]10

data[2]98

ta[4]107

data[3]65

Menyisipkan elemen array

import javax.swing.JOptionPane;
public class SisipArray {


ring[] args) {

 int[] data = new int[5];
 public static void main(S
t
 //int[] temporary = new int[data.length+1];


{
 data[index] = (int) (Math.random()*100)+20;
 }
 for(int index=0; index < data.length; index++)
 

 System.out.println("Data awal");
 System.out.println("---------");


ata" + "[" + index + "]" + " = " + data[index]);

 for(int index=0; index < data.length; index++) {
 System.out.println("
d }

 int sisip = Integer.parseInt(JOptionPane.showInputDialog(null, "Data yang ditambahkan:"));

<0 || lokasi>data.length-1) {
 JOptionPane.showMessageDialog(null, "anda salah meng-
 int lokasi = Integer.parseInt(JOptionPane.showInputDialog(null, "Pada index ke:"));

 if (lokas
iinputkan index");
 } else {
 int[] temporary = new int[data.length+1];
 for(int index=0; index < lokasi; index++){
 temporary[index] = data[index];
 }
 temporary[lokasi] = sisip;

a[index] = temporary[index];
 }
 }

 System.out.print
 for(int index=lokasi; index < data.length; index++){
 temporary[index+1] = data[index];
 }
 data = new int[temporary.length];
 for (int index=0; index<data.length; index++) {
 da
tln(" ");
 System.out.println("Setelah penyisipan");
 System.out.println("------------------");
 for(int index=0; index<data.length; index++) {
 System.out.println("data" + "[" + index + "]" + " = " + data[index]);
 }
 }


}
