How can I run method from MainActivity to my value class?

Question

I have 2 classes. I want to do that I can call method from value to MainActivity , I don't know if I need to use interface (I don't know how to use interface)

MainActivity class:

public class MainActivity extends Activity {
    public void name() { 
        if (Check(display_ContactsName, C) == true) {

        }
     }
 }

value class:

public class Values extends MainActivity {
    private boolean Check(String Name, Cursor C) {

    } 
}

Please look up Java naming convention... You'll benefit from using it. — ppeterka, Sep 23 '13 at 12:26

Values class extends MainActivity so no need to create interface.You can call any method of MainActivty directly just using method name.Even you can override any method of MainActivty in your Values class.

public class MainActivity extends Activity 
{
public String caption="";

//Method 1           
public void setCaption(String caption)
{
this.caption=caption
}
//Method 2           
public String getCaption()
{
return caption;
}

}

public class Values extends MainActivity 
{
setCaption("Test Application");
Toast.makeText(getApplicationContext(),getCaption(),Toast.LENGTH_SHORT).show();
}
