The java.util.concurrent.LinkedTransferQueue.put() method is an in-built function in Java which is used to insert an element in this queue. It waits till the space becomes available if queue is full.
Syntax:
LinkedTransferQueue.put(E e)
Parameters: The function accepts a single parameter e i.e. the element to be inserted.
Return Value: The function does not return anything.
Exception: The function shows NullPointerException when the specified element is Null.
Below programs illustrate the LinkedTransferQueue.put() method:
Program 1: Inserting Integers in the queue.
import java.util.concurrent.*;
class LinkedTransferQueuePutExample1 {
public static void main(String[] args)
{
LinkedTransferQueue<Integer> queue =
new LinkedTransferQueue<Integer>();
for ( int i = 10 ; i <= 15 ; i++)
queue.put(i);
System.out.println( "The elements in the queue are:" );
for (Integer i : queue)
System.out.print(i + " " );
}
}
|
Output:
The elements in the queue are:
10 11 12 13 14 15
Program 2: Adding String in the queue.
import java.util.concurrent.*;
class LinkedTransferQueuePutExample2 {
public static void main(String[] args)
{
LinkedTransferQueue<String> queue =
new LinkedTransferQueue<String>();
queue.put( "alex" );
queue.put( "bob" );
queue.put( "chuck" );
queue.put( "drake" );
queue.put( "erick" );
System.out.println( "The elements in the queue are:" );
for (String i : queue)
System.out.print(i + " " );
}
}

Output:
