Syntax

ObjectInputStream.resolveProxyClass(String [] interfaces) has the following syntax.

protected Class<?> resolveProxyClass(String[] interfaces)
               throws IOException,
                      ClassNotFoundException 

Example

In the following code shows how to use ObjectInputStream.resolveProxyClass(String [] interfaces) method.

//from   w w w. j a v a2  s  . co  m

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;

public class Main extends ObjectInputStream {

  public Main(InputStream in) throws IOException {
    super(in);
  }

  public static void main(String[] args) throws Exception {

    String s = "Hello World from java2s.com";

    FileOutputStream out = new FileOutputStream("test.txt");
    ObjectOutputStream oout = new ObjectOutputStream(out);


    oout.writeUTF(s);
    oout.flush();
    oout.close();
    
    Main ois = new Main(new FileInputStream("test.txt"));

    String[] list = { Serializable.class.getName() };

    System.out.println(ois.resolveProxyClass(list));
    ois.close();
  }
}

The code above generates the following result.
