LinkedBlockingQueue toString() method in Java
Last Updated :
18 Sep, 2018
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:
import java.util.concurrent.LinkedBlockingQueue;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
LinkedBlockingQueue<Integer> LBQ
= new LinkedBlockingQueue<Integer>();
LBQ.add( 7855642 );
LBQ.add( 35658786 );
LBQ.add( 5278367 );
LBQ.add( 74381793 );
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:
import java.util.concurrent.LinkedBlockingQueue;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
LinkedBlockingQueue<String> LBQ
= new LinkedBlockingQueue<String>();
LBQ.add( "gopal" );
LBQ.add( "gate" );
LBQ.add( "GRE" );
LBQ.add( "CAT" );
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]
