The toString() method of LinkedBlockingQueue 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 LinkedBlockingQueue:
Program 1:
// Java Program Demonstrate toString()// method of LinkedBlockingQueue import java.util.concurrent.LinkedBlockingQueue;import java.util.*; public class GFG { public static void main(String[] args) { // create object of LinkedBlockingQueue LinkedBlockingQueue<Integer> LBQ = new LinkedBlockingQueue<Integer>(); // Add numbers to end of LinkedBlockingQueue LBQ.add(7855642); LBQ.add(35658786); LBQ.add(5278367); LBQ.add(74381793); // Print the queue System.out.println("Linked Blocking Queue: " + LBQ); System.out.println("Linked Blocking Queue in string " + LBQ.toString()); }} |
Output:
Linked Blocking Queue: [7855642, 35658786, 5278367, 74381793] Linked Blocking Queue in string [7855642, 35658786, 5278367, 74381793]
Program 2:
// Java Program Demonstrate toString()// method of LinkedBlockingQueue import java.util.concurrent.LinkedBlockingQueue;import java.util.*; public class GFG { public static void main(String[] args) { // create object of LinkedBlockingQueue LinkedBlockingQueue<String> LBQ = new LinkedBlockingQueue<String>(); // Add numbers to end of LinkedBlockingQueue LBQ.add("gopal"); LBQ.add("gate"); LBQ.add("GRE"); LBQ.add("CAT"); // Print the queue System.out.println("Linked Blocking Queue: " + LBQ); System.out.println("Linked Blocking Queue in string " + LBQ.toString()); }} |
Output:
Linked Blocking Queue: [gopal, gate, GRE, CAT] Linked Blocking Queue in string [gopal, gate, GRE, CAT]
