How to pass an object from one Activity to another in Android?

This example demonstrates how do I pass an object from one Activity to another in android.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".MainActivity">
   <Button
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Click here to pass object to Second Activity!"
      android:id="@+id/button"
      android:layout_centerInParent="true" />
</RelativeLayout>
Step 3 − Create a java class and add the following code in Character.java
import java.io.Serializable;
public class Character implements Serializable {
   String name, Proffession, Position;
   String[] abilities;
   public Character(String name, String proffession, String position, String[] abilities) {
      this.name = name;
      Proffession = proffession;
      Position = position;
      this.abilities = abilities;
   }
}
Step 4 − Add the following code to MainActivity.java
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      Button button = (Button) findViewById(R.id.button);
      button.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
            Character sports = new Character("CR7", "Football", "Left Winger", new String[]{"Best Freeckicker in the World"});
            intent.putExtra("Character", sports);
            startActivity(intent);
         }
      });
   }
}
Step 5 − Create an emty activity, name it as SecondActivity and add the following code in SecondActivity.java
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
import java.util.Arrays;
public class SecondActivity extends AppCompatActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_second);
      Character sports = (Character)getIntent().getSerializableExtra("Character");
      TextView textView = findViewById(R.id.textView);
      textView.setText(sports.name +"\n" + sports.Proffession + "\n" + sports.Position+ "\n" + Arrays.toString(sports.abilities));
   }
}
Step 6 − Add the following code in activity_second.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".SecondActivity">
   <TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:id="@+id/textView"
      android:textSize="20sp"
      android:layout_centerInParent="true"/>
</RelativeLayout>
