The toString() method of CopyOnWriteArrayList returns the string representation of the list.
Syntax:
public String toString()
Parameters: The function does not accepts any parameter.
Return Value: The function returns the string representation of the list.
Below programs illustrate the above function:
Program 1:
// Java Program to illustrate the CopyOnWriteArrayList// toString() method in Javaimport java.util.concurrent.CopyOnWriteArrayList;import java.util.*;  public class GFG {    public static void main(String[] args)    {          // create object of CopyOnWriteArrayList        CopyOnWriteArrayList<Integer> ArrLis            = new CopyOnWriteArrayList<Integer>();          // Add elements        ArrLis.add(32);        ArrLis.add(67);        ArrLis.add(98);        ArrLis.add(100);          // print CopyOnWriteArrayList        System.out.println("CopyOnWriteArrayList: "                                           + ArrLis);          System.out.println("ArrLis converted to string: "                                     + ArrLis.toString());    }} |
Output:
CopyOnWriteArrayList: [32, 67, 98, 100] ArrLis converted to string: [32, 67, 98, 100]
Program 2:
// Java Program to illustrate the CopyOnWriteArrayList// toString()() method in Javaimport java.util.concurrent.CopyOnWriteArrayList;import java.util.*;  public class GFG {    public static void main(String[] args)    {          // create object of CopyOnWriteArrayList        CopyOnWriteArrayList<String> ArrLis            = new CopyOnWriteArrayList<String>();          // Add elements        ArrLis.add("gopal");        ArrLis.add("gfg");        ArrLis.add("jgec");        ArrLis.add("sudo");          // print CopyOnWriteArrayList        System.out.println("CopyOnWriteArrayList: " + ArrLis);          System.out.println("ArrLis converted to string: "                                       + ArrLis.toString());    }} |
Output:
CopyOnWriteArrayList: [gopal, gfg, jgec, sudo] ArrLis converted to string: [gopal, gfg, jgec, sudo]
