สอบถามเรื่องการรับส่งค่า String ข้าม Class โดยการเรียกใช้ ****ไม่ใช้ Intent นะครับ****** (มือใหม๋)

public class Main1 extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		

		final EditText Name1 = (EditText) findViewById(R.id.editTextName);
		final EditText Last1 = (EditText) findViewById(R.id.editTextLast);
		final EditText Age1 = (EditText) findViewById(R.id.editTextAge);
		final Button Run = (Button) findViewById(R.id.button1);
		

		Run.setOnClickListener(new View.OnClickListener() {
			public void onClick(View v) {

				Intent intent = new Intent(Main1.this, Main2.class);
				startActivity(intent);
			}
		});

	}

}

public class Main2 extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main2);

		final Data main2 = new Data();
		main2.Name.getClass();
		main2.Last.getClass();
		main2.Age.getClass();

		final EditText Name = (EditText) findViewById(R.id.editTextName);
		final EditText Last = (EditText) findViewById(R.id.editTextLast);
		final EditText Age = (EditText) findViewById(R.id.editTextAge);
		final Button Run = (Button) findViewById(R.id.button1);

		Run.setOnClickListener(new View.OnClickListener() {
			public void onClick(View v) {

				Name.setText(main2.Name);
				Last.setText(main2.Last);
				Age.setText(main2.Age);
			}
		});

	}

}

public class Data {
	
	public String Name = "แมว";
	public String Last = "ปลา";
public String Age = "30";

}
