How to serialize-deserialize an object in java


Serializing an Java Object:
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
public class JavaSerializationExample {

   public static void main(String[] args) {
	   
	  String programmingLanguages[] = new String[5];
	  programmingLanguages[0] = "Java";
	  programmingLanguages[1] = "JavaScript";
	  programmingLanguages[2] = "Php";
	  programmingLanguages[3] = "DotNet";
	  programmingLanguages[4] = "C++";
	  
      
      try {
    	 System.out.println("Serializing object ProgrammingLanguages ");
         FileOutputStream fileOutputStream = new FileOutputStream("languages.ser");
         ObjectOutputStream objectOutputStream = new ObjectOutputStream(fileOutputStream);
         objectOutputStream.writeObject(programmingLanguages);
         objectOutputStream.close();
         fileOutputStream.close();
         System.out.println("Serialized object Stored as ProgrammingLanguages.ser ");
      }catch(IOException e) {
         e.printStackTrace();
      }
   }
}
Deserializing a Java Object:
import java.io.FileInputStream;
import java.io.IOException;
import java.io.ObjectInputStream;

public class JavaSerializationExample {

   public static void main(String[] args) {
	   
	  String programmingLanguages[] = new String[5];
      
      try {
    	 System.out.println("Deserializing object ProgrammingLanguages ");
    	 FileInputStream fileInputStream = new FileInputStream("languages.ser");
         ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream);
         try {
			programmingLanguages =  (String[]) objectInputStream.readObject();
		} catch (ClassNotFoundException e1) {
			e1.printStackTrace();
		}
         objectInputStream.close();
         fileInputStream.close();

         for (int i = 0; i < programmingLanguages.length; i++) {
			System.out.println(programmingLanguages[i]);
		}
      }catch(IOException e) {
         e.printStackTrace();
      }
   }
} 
Output:
