如何只获取 jlabel 的图像图标名称而不是路径

Question

我想知道如何只获取 JLabel 图像名称而不是整个路径，我尝试使用

jLabel.getIcon();

但它使用整个路径而不仅仅是名称（即名称，berries.png）。当我使用 getIcon() 时，结果是：

file:/C:/Users/lolne/Desktop/FCaWfD%20-%20Desktop%20Updated%20Version/build/classes/resources/quiz/berries.png

我只希望找到 berries.png 的结尾部分。我将此代码用于学校作业的食物网络游戏，这是使用它的代码：

public void checkResults(){

    JLabel[] consumers = {
        consumer1,
        consumer2,
        consumer3,
        consumer4,
        consumer5,
    };

    switch(RandomNumber.randomNumber){
        case 1:
            if(producer.getIcon().equals(producers[0])){
                correct++;
            }else{
                producer.setBorder(BorderFactory.createLineBorder(Color.RED));
            }

            for(int i = 0; i < 5; i++){
                if(consumers[i].getIcon().equals(consumers1.get(i))){
                    correct++;
                }else{
                    consumers[i].setBorder(BorderFactory.createLineBorder(Color.RED));
                }
            }
        break;

        case 2:
            if(producer.getIcon().equals(producers[1])){
                correct++;
            }else{
                producer.setBorder(BorderFactory.createLineBorder(Color.RED));
            }

            for(int i = 0; i < 5; i++){
                if(consumers[i].getIcon().equals(consumers2.get(i))){
                    correct++;
                }else{
                    consumers[i].setBorder(BorderFactory.createLineBorder(Color.RED));
                }
            }
        break;

        case 3:
            if(producer.getIcon().equals(producers[2])){
                correct++;
            }else{
                producer.setBorder(BorderFactory.createLineBorder(Color.RED));
            }

            for(int i = 0; i < 5; i++){
                if(consumers[i].getIcon().equals(consumers3.get(i))){
                    correct++;
                }else{
                    consumers[i].setBorder(BorderFactory.createLineBorder(Color.RED));
                }
            }
        break;
    }
}

总而言之，我的问题是，"How do I get the name of the image itself rather than the whole path of the image"

Answer 1

您可以使用 file getName() 方法来获取文件的名称

File file = new File("C:/Users/lolne/Desktop/FCaWfD%20-%20Desktop%20Updated%20Version/build/classes/resources/quiz/berries.png");
        System.out.println(file.getName());

会输出

berries.png

如何只获取 jlabel 的图像图标名称而不是路径

How do you get just the image icon name of a jlabel rather than the path
