二进制存储和其他的存储一样,都是由 FileOutPutStream 流 写入文件
public static void main(String[] args) {
// TODO Auto-generated method stub
File file = new File(".\\test.dat");
//TestClass 实体类
TestClass tc = new TestClass(5,"akldsj");
try {
//判断文件是否存在
if(!file.exists()) file.createNewFile();
//FileOutputStream 文件写入流
FileOutputStream fos = new FileOutputStream(file);
//二进制流写入
//写入二进制文件
oos.writeObject(tc);
System.out.println("文件已存入");
oos.close();
fos.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//赌取二进制文件
try {FileInputStream fis = new FileInputStream(file);
ObjectInputStream ois = new ObjectInputStream(fis);
TestClass tb = (TestClass)ois.readObject();
System.out.println(tb);
ois.close();
fis.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
