Example

The following example shows the usage of java.util.ArrayList.clone() method.

package com.c4learn.arraylist;
import java.util.ArrayList;
public class ArrayListExamples {
  public static void main(String args[]) {
    // Create ArrayList 1
    ArrayList<String> arrlist1 = new ArrayList<String>(5);
    // Fill Elements in ArrayList 1
    arrlist1.add("A");
    arrlist1.add("B");
    arrlist1.add("C");
    // Print Elements in ArrayList 1
    System.out.println("ArrayList 1 : " + arrlist1);
    // Clone Operation
    ArrayList<String> arrlist2 = (ArrayList<String>) arrlist1.clone();
    System.out.println("ArrayList 2 : " + arrlist2);
  }
}

package com.c4learn.arraylist;

import java.util.ArrayList;

public class ArrayListExamples {

public static void main(String args[]) {

// Create ArrayList 1

ArrayList<String> arrlist1 = new ArrayList<String>(5);

// Fill Elements in ArrayList 1

arrlist1.add("A");

arrlist1.add("B");

arrlist1.add("C");

// Print Elements in ArrayList 1

System.out.println("ArrayList 1 : " + arrlist1);

// Clone Operation

ArrayList<String> arrlist2 = (ArrayList<String>) arrlist1.clone();

System.out.println("ArrayList 2 : " + arrlist2);

}

Output :

ArrayList 1 : [A, B, C]
ArrayList 2 : [A, B, C]

1 2	ArrayList 1 : [A, B, C] ArrayList 2 : [A, B, C]
