关于java.io.EOFException产生的原因以及解决方案

ObjectInputStream objectInputStream=null;
        ArrayList<Student> students=null;
        try {
            objectInputStream = new ObjectInputStream(new FileInputStream("D:\\桌面\\java38\\javase08\\java08\\1.txt"));
            students = (ArrayList<Student>) objectInputStream.readObject();
            System.out.println("数据载入成功");
​
        }catch (Exception e) {
            e.printStackTrace();
            System.out.println("数据载入失败");
        }

ObjectInputStream objectInputStream=null;
//idea上显示null为灰色，说明 new ObjectInputStream(new FileInputStream("D:\\桌面\\java38\\javase08\\java08\\1.txt"));返回值为null，即文件"D:\\桌面\\java38\\javase08\\java08\\1.txt"为空
objectInputStream = new ObjectInputStream(new FileInputStream("D:\\桌面\\java38\\javase08\\java08\\1.txt"));

        ObjectInputStream objectInputStream=null;
        ArrayList<Student> students=null;
        try {
            objectInputStream = new ObjectInputStream(new FileInputStream("D:\\桌面\\java38\\javase08\\java08\\1.txt"));
            students = (ArrayList<Student>) objectInputStream.readObject();
            System.out.println("数据载入成功");
​
        } catch (EOFException e) {
            students = new ArrayList<>();
​
        }catch (Exception e) {
            e.printStackTrace();
            System.out.println("数据载入失败");
        } finally {
            if(objectInputStream != null) {
                objectInputStream.close();
            }

students = (ArrayList<Student>) objectInputStream.readObject();
