Java 使用3个队列分别保留手机最近10个“未接来电”、“已接来电”、“以拨电话”

下面是Java代码实现：

import java.util.ArrayDeque;
import java.util.Queue;

public class PhoneCallQueue {
    private Queue<String> missedCalls = new ArrayDeque<>();
    private Queue<String> receivedCalls = new ArrayDeque<>();
    private Queue<String> dialedCalls = new ArrayDeque<>();

    public void addMissedCall(String number) {
        missedCalls.offer(number);
        if (missedCalls.size() > 10) {
            missedCalls.poll();
        }
    }

    public void addReceivedCall(String number) {
        receivedCalls.offer(number);
        if (receivedCalls.size() > 10) {
            receivedCalls.poll();
        }
    }

    public void addDialedCall(String number) {
        dialedCalls.offer(number);
        if (dialedCalls.size() > 10) {
            dialedCalls.poll();
        }
    }

    public void displayAllCalls() {
        System.out.println("Missed calls:");
        for (String number : missedCalls) {
            System.out.println(number);
        }
        System.out.println("Received calls:");
        for (String number : receivedCalls) {
            System.out.println(number);
        }
        System.out.println("Dialed calls:");
        for (String number : dialedCalls) {
            System.out.println(number);
        }
    }

    public static void main(String[] args) {
        PhoneCallQueue phone = new PhoneCallQueue();
        phone.addMissedCall("1234567890");
        phone.addMissedCall("2345678901");
        phone.addReceivedCall("3456789012");
        phone.addReceivedCall("4567890123");
        phone.addDialedCall("5678901234");
        phone.addDialedCall("6789012345");
        phone.displayAllCalls();
    }
}

在这个实现中，我们使用了三个队列 `missedCalls`、`receivedCalls`、`dialedCalls` 分别保存未接来电、已接来电和已拨电话。每次添加新的号码时，我们都检查队列的大小是否超过了10个，如果超过了就从队头弹出一个元素。最后，我们编写了一个 `displayAllCalls()` 方法来打印出所有电话。在 `main()` 方法中，我们添加了一些测试数据并调用 `displayAllCalls()` 方法来验证实现的正确性。
