Question: Serialize Java to File? How can I in Java store and retrieve serialized objects to and from a file?

I have a .txt file and two String objects say,

String company = "Company",
String company_name = "Comp_name",

How do I that?

Answer: I found one example how to write a serialized object to a file in Java, (file tmp). The file tmp will be in the same directory as the program:


import java.io.*; 
import java.util.*; 
// Writing an object. 
// Serialize today's date to a file. 
 
public class WriteData implements Serializable { 
    public static void main(String[] args) throws IOException { 
        FileOutputStream f = new FileOutputStream("tmp"); 
        ObjectOutputStream s = new ObjectOutputStream(f); 
        String company = "My Good Company"; 
        s.writeObject(company); 
        s.flush(); 
    } 
} 
Here is an example of how to read a serialized object from the 
        file "tmp": 
        import java.io.*; 
import java.util.*; 
import java.lang.*; 
// Reading an Object from a stream. 
// Deserialize a String and date from a file. 
 
public class ReadData implements Serializable { 
    public static void main(String[] args) 
            throws IOException, ClassNotFoundException { 
        FileInputStream in = new FileInputStream("tmp"); 
        ObjectInputStream s = new ObjectInputStream(in); 
        String company = ""; 
        String company_name = ""; 
        company = (String) s.readObject(); 
        System.out.println(company + " "); 
    } 
}
