Java write string to text file code example
1、 Filewriter and file -- write string to text file
2、 InputStream and OutputStream input and output streams
3、 Objectoutputstream and objectinputstream
Objectoutputstream writes the basic data types and graphics of Java objects to OutputStream. Objects can be read (reconstructed) using objectinputstream. Persistent storage of objects can be achieved by using files in the stream.
Writes serialized objects to a file
1. Writes serialized objects to a file
FileOutputStreamfileStream=newFileOutputStream(“Myobject.ser”);// If it does not exist, it is created automatically
2. Create objectoutputstream
ObjectOutputStreamos=newObjectOutputStream(fileStream);
3. Write object
os. writeObject(one);// One is the reference name of an object instance
4. Close objectoutputstream
os. close
Objectinputstream is used to deserialize
Deserialization
1. Create FileInputStream
FileInputStreamfileStream=newFileInputStream(“MyObject.ser”);
2. Create objectinputstream
ObjectInputStreamos=newObjectInputStream(fileStream);
3. Read object
Objectone=os. readObject();
4. Convert object type
Modelelf=(Model)one;// Model is the class name of the one object
5. Close objectinputstream
os. close();
