java.util.concurrent.ConcurrentLinkedDeque.addLast()是Java中的内置函数,它将指定的元素插入双端队列的末尾。
用法:
conn_linked_deque.addLast(elem)
参数:该方法仅接受要添加到ConcurrentLinkedDeque末尾的单个参数elem。
返回值:该函数没有返回值。
异常:当传递给函数的参数为null时,该方法将引发NullPointerException。由于其有限的性质,此方法将永远不会引发IllegalStateException或返回false。
以下程序说明了java.util.concurrent.ConcurrentLinkedDeque.addLast()方法的用法:
示例1:该程序涉及一个Integer类型的ConcurrentLinkedDeque。
// Java Program Demonstrate addLast()
// method of ConcurrentLinkedDeque
import java.util.concurrent.*;
class ConcurrentLinkedDequeDemo {
public static void main(String[] args)
{
ConcurrentLinkedDeque<Integer> cld =
new ConcurrentLinkedDeque<Integer>();
cld.addLast(12);
cld.addLast(110);
cld.addLast(55);
cld.addLast(76);
// Displaying the existing LinkedDeque
System.out.println("Initial Elements in"
+ "the LinkedDeque: " + cld);
// Insert a new element in the LinkedDeque
cld.addLast(21);
// Displaying the modified LinkedDeque
System.out.println("Initial Elements in"
+ "the LinkedDeque: " + cld);
}
}
输出:
Initial Elements inthe LinkedDeque: [12, 110, 55, 76] Initial Elements inthe LinkedDeque: [12, 110, 55, 76, 21]
示例2:当将null作为参数传递给函数时,此程序涉及一个带有异常处理的Integer类型的ConcurrentLinkedDeque。
// Java Program Demonstrate addLast()
// method of ConcurrentLinkedDeque
import java.util.concurrent.*;
class ConcurrentLinkedDequeDemo {
public static void main(String[] args)
{
ConcurrentLinkedDeque<String> cld =
new ConcurrentLinkedDeque<String>();
cld.addLast("Geeks");
cld.addLast("Geek");
cld.addLast("Gfg");
cld.addLast("Contribute");
// Displaying the existing LinkedDeque
System.out.println("Initial Elements in"
+ "the LinkedDeque: " + cld);
/* Exception thrown when null
is passed as parameter*/
try {
cld.addLast(null);
}
catch (NullPointerException e) {
System.out.println("NullPointerException"
+ "thrown");
}
// Insert a new element in the LinkedDeque
cld.addLast("Sudo Placement");
// Displaying the modified LinkedDeque
System.out.println("Initial Elements in"
+ "the LinkedDeque: " + cld);
}
}
输出:
Initial Elements inthe LinkedDeque: [Geeks, Geek, Gfg, Contribute] NullPointerExceptionthrown Initial Elements inthe LinkedDeque: [Geeks, Geek, Gfg, Contribute, Sudo Placement]
