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 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()); } } |
Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793] LBD in string [7855642, 35658786, 5278367, 74381793]
Program 2:
// 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()); } } |
Linked Blocking Deque: [geeks, sudo, gate, gopal] LBD in string [geeks, sudo, gate, gopal]
