Mengurutkan Elemen Array

public class DataSort {

 public static void main(String[] args) {

 int[] data = new int[5];

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

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

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

 System.out.println();

 for(int x=0; x<data.length-1; x++) {
 for(int y=x+1; y<data.length; y++){
 if(data[x] > data[y]) {
 int temp = data[x];
 data[x] = data[y];
 data[y] = temp;
 }
 }
 }
 System.out.println("Data setelah diurutkan");
 System.out.println("----------------------");
 for(int z=0; z<data.length; z++){
 System.out.println("data" + "[" + z + "]" + " = " + data[z]);
 }
 System.out.println();
 }
}

output program:

Data awal
---------
data[0] = 7
data[1] = 89
data[2] = 47
data[3] = 89
data[4] = 6
Data setelah diurutkan
----------------------
data[0] = 6
data[1] = 7
data[2] = 47
data[3] = 89
data[4] = 89
