声明
以下是java.util.ArrayDeque.remove(o)方法的声明
public boolean remove(Object o)
参数
-
o%uA0-- 要从此deque队列移除的元素，如果存在的话
返回值
如果此deque 队列包含指定的元素，此方法返回true。
异常

NA
例子
下面的示例演示java.util.ArrayDeque.remove(o)方法的用法。
package com.yiibai import java.util.ArrayDeque import java.util.Deque public class ArrayDequeDemo { public static void main(String[] args) { // create an empty array deque with an initial capacity Deque<Integer> deque = new ArrayDeque<Integer>(8) // use add() method to add elements in the deque deque.add(25) deque.add(30) deque.add(20) deque.add(40) // printing all the elements available in deque for (Integer number : deque) { System.out.println("Number = " + number) } // deque contains element 30, returns true boolean retval = deque.remove(30) if (retval == true) { System.out.println("element 30 is removed from the deque") } else { System.out.println("element 30 is not contained in the deque") } // deque does not contain element 15, returns false boolean retval = deque.remove(15) if (retval == true) { System.out.println("element 15 is removed from the deque") } else { System.out.println("element 15 is not contained in the deque") } // printing remaining elements for (Integer number : deque) { System.out.println("Number = " + number) } } }
让我们来编译和运行上面的程序，这将产生以下结果：
Number = 25 Number = 30 Number = 20 Number = 40 element 30 is removed from the deque element 15 is not contained in the deque Number = 25 Number = 20 Number = 40
