In Code Sample:How to write a class that reads the objects that have been saved, and invokes a method ?
Write a class that reads the objects that
have been saved, and invokes a method as shown in Code Sample.
Again, as with writeObject , the readObject
method can be called any number of times to read any
number of objects from the input stream.
Code Sample: ReadInfo.java
import java.io.*;
import java.util.Date;
public class ReadInfo {
public static void main(String argv[]) throws Exception {
FileInputStream fis = new FileInputStream("name.out");
ObjectInputStream ois = new ObjectInputStream(fis);
// read the objects from the input stream (the file name.out)
UserInfo user1 = (UserInfo) ois.readObject();
UserInfo user2 = (UserInfo) ois.readObject();
// invoke a method on the constructed object
user1.printInfo();
user2.printInfo();
ois.close();
fis.close();
}
}
To try out this example, compile the source files:
UserInfo.java , SaveInfo.java ,
and ReadInfo.java . Run SaveInfo ,
then ReadInfo , and you would see some output
similar to this:
The name is: Java Duke
The name is: Java Blue
