java - 一个 ArrayList 添加 2 个不同的选项

Question

我的问题是我必须使用一个 Arraylist 并添加两个选项

1.任务(内容、开始时间、开始结束、难度)

contents- String
startTime,startEnd- Localtime
difficulty- boolean easy/difficult

发生的事情(内容、开始时间、开始结束、重要、训练)

contents- String
startTime,startEnd- Localtime
important- boolean Yes/No
training- boolean  Yes/No

是否可以将两个不同的选项合并到一个数组列表中？

Answer 1

通用属性接口(interface)

public interface MyI {

    public String getContens();

    public LocalTime getStartTime();

    public LocalTime getStartEnd();

}

然后为独特实例的覆盖范围创建模型:

public class Task implements MyI {

    private String contens;

    private LocalTime startTime;

    private LocalTime startEnd;

    private boolean difficulty;

    public boolean isDifficulty() {
        return difficulty;
    }

    public void setDifficulty(boolean difficulty) {
        this.difficulty = difficulty;
    }

    public void setContens(String contens) {
        this.contens = contens;
    }

    public void setStartTime(LocalTime startTime) {
        this.startTime = startTime;
    }

    public void setStartEnd(LocalTime startEnd) {
        this.startEnd = startEnd;
    }

    @Override
    public String getContens() {
        return this.contens;
    }

    @Override
    public LocalTime getStartTime() {
        return this.startTime;
    }

    @Override
    public LocalTime getStartEnd() {
        return this.startEnd;
    }

}

public class Happening implements MyI {

    private String contens;

    private LocalTime startTime;

    private LocalTime startEnd;

    private boolean important;

    private boolean training;

    public boolean isImportant() {
        return important;
    }

    public void setImportant(boolean important) {
        this.important = important;
    }

    public boolean isTraining() {
        return training;
    }

    public void setTraining(boolean training) {
        this.training = training;
    }

    public void setContens(String contens) {
        this.contens = contens;
    }

    public void setStartTime(LocalTime startTime) {
        this.startTime = startTime;
    }

    public void setStartEnd(LocalTime startEnd) {
        this.startEnd = startEnd;
    }

    @Override
    public String getContens() {
        return this.contens;
    }

    @Override
    public LocalTime getStartTime() {
        return this.startTime;
    }

    @Override
    public LocalTime getStartEnd() {
        return this.startEnd;
    }

}

现在您可以使用界面创建一个列表来保存两种类型的模型:

List<MyI> myList = new ArrayList<MyI>();
