java - 如何编写扫描仪代码来加载先前保存在 save.txt 中的内容？

Question

我的目标是加载 save.txt 文件中的内容。我该怎么写呢？我不确定我的写入代码是否正在写入 save.txt。可以看一下吗？

else if (savePicture.isPointInElement(clickX, clickY)){
    FileWriter fw = new FileWriter("save.txt");
    for (int i = 0; i < arraysticker.length; i++){
        if (arraysticker[image]!=null){
            String name;
            int x,y;
            name = sticker.getname();
            x = sticker.getx();
            y = sticker.gety();
            fw.write(name + " " + x + " " + y + "\n");
        }
    }
}

这是我添加的“贴纸”代码之一。

if (hatSoundPlay){ //if hatSoundPlay is true
    hatsound.play(); //and a hatsound will play
    sticker sticker1 = new sticker();//creates a new sticker1
    sticker1.arraysticker(hatPicture, "hat.png", clickX, clickY);//places sticker
    image ++;//increments image by 1
    arraysticker[image] = sticker1;//puts sticker 4 into the array
    sticker11 = true;

Answer 1

FileWriter fw = new FileWriter("save.txt");
for (int i = 0; i < arraysticker.length; i++){
    if (arraysticker[image]!=null){
        String name;
        int x,y;
        name = sticker.getname();
        x = sticker.getx();
        y = sticker.gety();
        fw.write(name + " " + x + " " + y + "\n");
    }
}
**fw.flush();
fw.close();**
