LinkedBlockingDeque的forEach()方法为Iterable的每个元素执行给定的操作,直到处理完所有元素或该操作引发异常为止。
用法:
public void forEach(Consumer<E> action)
参数:此方法采取参数操作,该参数操作表示要对每个元素执行的操作。
返回值:此方法不返回任何内容。
异常:如果指定的操作为null,则此方法将引发NullPointerException。
以下示例程序旨在说明LinkedBlockingDeque类的forEach()函数:
例:
// Java Program Demonstrate forEach()
// method of LinkedBlockingDeque
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws IllegalStateException
{
// create object of LinkedBlockingDeque
LinkedBlockingDeque<Integer> LBD
= new LinkedBlockingDeque<Integer>();
// Add numbers to end of LinkedBlockingDeque
LBD.add(11);
LBD.add(22);
LBD.add(33);
LBD.add(44);
LBD.add(55);
LBD.add(66);
LBD.add(77);
// print deque
System.out.println("Linked Blocking Deque: "
+ LBD);
System.out.println("Traversing this Deque: ");
// Traverse this queue using forEach() method
LBD.forEach((n) -> System.out.println(n));
}
}
输出:
Linked Blocking Deque: [11, 22, 33, 44, 55, 66, 77] Traversing this Deque: 11 22 33 44 55 66 77
示例:2
// Java Program Demonstrate forEach()
// method of LinkedBlockingDeque
import java.util.concurrent.LinkedBlockingDeque;
import java.util.*;
public class GFG {
public static void main(String[] args)
throws IllegalStateException
{
// create object of LinkedBlockingDeque
LinkedBlockingDeque<String> LBD
= new LinkedBlockingDeque<String>();
// Add elements to end of LinkedBlockingDeque
LBD.add("GeeksforGeeks");
LBD.add("Gfg");
LBD.add("Geeks");
LBD.add("Computer");
LBD.add("Science");
LBD.add("Portal");
// print deque
System.out.println("Linked Blocking Deque: "
+ LBD);
System.out.println("Traversing this deque: ");
// Traverse this deque using forEach() method
LBD.forEach((n) -> System.out.println(n));
}
}
输出:
Linked Blocking Deque: [GeeksforGeeks, Gfg, Geeks, Computer, Science, Portal] Traversing this deque: GeeksforGeeks Gfg Geeks Computer Science Portal
