How To Write A Class That Reads The Objects That Have Been Saved, And Invokes A Method


  • 7 Dec, 2011

    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.javaimport 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 objectuser1.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 DukeThe name is: Java Blue
