Berikut ini adalah contoh program untuk menampilkan nilai arraylist yang sudah diacak menggunakan methods dari class Collection yaitu Collections.shuffle(arraylist),  mari kita lihat contoh programnya

Nama file : shuffle_ArrayList.java

import java.util.ArrayList;
import java.util.Collections;

public class shuffle_ArrayList {

  public static void main(String[] args) {
   
    //create an ArrayList object
    ArrayList arrayList = new ArrayList();
   
    //Add elements to Arraylist
    arrayList.add("A");
    arrayList.add("B");
    arrayList.add("C");
    arrayList.add("D");
    arrayList.add("E");
   
    System.out.println("Before shuffling, ArrayList contains : " + arrayList);
   
    Collections.shuffle(arrayList);
   
    System.out.println("After shuffling, ArrayList contains : " + arrayList);
   
  }
}    

Output

run:

Before shuffling, ArrayList contains : [A, B, C, D, E]

After shuffling, ArrayList contains : [B, C, D, E, A]
