实现java跨平台,通用读取文件方法(window/linux系统)
作者:互联网
来看看代码的演进
一开始是写在windows系统中的盘符下,考虑到linux系统无盘符,但windows又没有root,只能存入内存中了,二者可兼得,这也实现了java的跨平台的特点。
try{
OutputStream out = new FileOutputStream("E:\\a.txt");
ObjectOutputStream oos = new ObjectOutputStream(out);
oos.writeObject(this);
oos.close();
InputStream in = new FileInputStream("E:\\a.txt");
ObjectInputStream ois = new ObjectInputStream(in);
Object clone = ois.readObject();
ois.close();
retrue clone;
}catch(Exception e){
throw new RuntimeException(e);
}
演进后,如下:
try{
ByteArrayOutputStream out = new ByteArrayOutputStream(); //这里使用写入内存的流
ObjectOutputStream oos = new ObjectOutputStream(out);
oos.writeObject(this);
oos.close();
//从内存中取出数据
byte[] bt = out.toByteArray(); //将内存中的字节取出来
InputStream in = new ByteArrayInputStream(bt);
ObjectInputStream ois = new ObjectInputStream(in);
Object clone = ois.readObject();
ois.close();
retrue clone;
}catch(Exception e){
throw new RuntimeException(e);
}
