How to change a value in another class?

Question

I’m trying to change the value of a variable in another class but I’m not getting it.

package com.cursoandroid.firebaseapp.novotestebanco;

public  class Logado {

   public String situacao;


    Logado(String situacao){
        this.situacao = "deslogado";
    }

    public  String getSituacao() {
        return situacao;
    }

    public void setSituacao(String situacao) {
        this.situacao = situacao;
    }
}




botaoMostrar.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Logado logado = new Logado("");
            logado.setSituacao("logado");
            mostrar.setText(logado.getSituacao());
            startActivity(new Intent(MainActivity.this, Mostrar.class));



        }
    });

Class Show

public class Mostrar extends AppCompatActivity {
    public TextView text;

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

        text = (TextView) findViewById(R.id.texto);

        Logado logado = new Logado("");
        text.setText(logado.getSituacao());
    }
}
