CopyOnWriteArrayList toString() method in Java

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 Java
import 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 Java
import 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]
