LinkedBlockingDeque toString() method in Java

The toString() method of LinkedBlockingDeque returns a string representation of this collection. The string representation consists of a list of the collection's elements in the order they are returned by its iterator, enclosed in square brackets ("[]"). The adjacent elements are separated by the characters ", " (comma and space). The elements are converted to strings as by String.valueOf(Object). Syntax:

public String toString()

Parameters: This method does not accept any parameters. Returns: This method returns a string representation of this collection. Below programs illustrate toString() method of LinkedBlockingDeque: Program 1:

Java

// Java Program Demonstrate toString()
// method of LinkedBlockingDeque

import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;

public class GFG {
    public static void main(String[] args)

    {

        // create object of LinkedBlockingDeque
        LinkedBlockingDeque<Integer> LBD
            = new LinkedBlockingDeque<Integer>();

        // Add numbers to end of LinkedBlockingDeque
        LBD.add(7855642);
        LBD.add(35658786);
        LBD.add(5278367);
        LBD.add(74381793);

        // Print the queue
        System.out.println("Linked Blocking Deque: " + LBD);

        System.out.println("LBD in string " + LBD.toString());
    }
}

Output:

Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]
LBD in string [7855642, 35658786, 5278367, 74381793]

Program 2:

Java

// Java Program Demonstrate toString()
// method of LinkedBlockingDeque

import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;

public class GFG {
    public static void main(String[] args)

    {

        // create object of LinkedBlockingDeque
        LinkedBlockingDeque<String> LBD
            = new LinkedBlockingDeque<String>();

        // Add numbers to end of LinkedBlockingDeque
        LBD.add("geeks");
        LBD.add("sudo");
        LBD.add("gate");
        LBD.add("gopal");

        // Print the queue
        System.out.println("Linked Blocking Deque: " + LBD);

        System.out.println("LBD in string " + LBD.toString());
    }
}

Output:

Linked Blocking Deque: [geeks, sudo, gate, gopal]
LBD in string [geeks, sudo, gate, gopal]
