Doubt abt Serialization

[Gowher Naik]

import java.io.*;
public class FileTest{
    public static void main(String argv[]) throws IOException{
FileTest o = new FileTest();
o.go();
    }
    public void go() throws IOException{
String[] obs = {"one","two","three"};
FileOutputStream out = new FileOutputStream("mystrings.ob");
ObjectOutputStream s = new ObjectOutputStream(out);
s.writeObject(obs);
s.flush();
    }
 
}

Above code doesnot throw Exception at run time.
it serialize string array(obs)without implementing Serializable interface.
According to me it should throw runtime Exception(NotSerializableException).

Thanks.

You are serializing a String array. It is the String array that has to be Serializable not class FileTest. If you print obs instanceof Serializable you will see that it returns true.

ok it means that String implements Serializable interface so TestFile
donot required to implement Serializable.

If TestFile class would be Serializing its data then Serializable interface would be required
is it so?
