I keep getting errors on both IDEs on this code task from initializing a button

What I've done

    Button Showfactbutton = (Button) findViewById(R.Id.showFactbutton);
}

What I get

./FunFactsActivity.java:16: error: ';' expected Button showFactButton Button = (Button) findViewById(R,Id.showFactButton); ^ ./FunFactsActivity.java:16: error: cannot find symbol Button showFactButton Button = (Button) findViewById(R,Id.showFactButton); ^ symbol: variable Button location: class FunFactsActivity ./FunFactsActivity.java:16: error: cannot find symbol Button showFactButton Button = (Button) findViewById(R,Id.showFactButton); ^ symbol: variable R location: class FunFactsActivity ./FunFactsActivity.java:16: error: cannot find symbol Button showFactButton Button = (Button) findViewById(R,Id.showFactButton); ^ symbol: variable Id location: class FunFactsActivity 4 errors

FunFactsActivity.java
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class FunFactsActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fun_facts);

        // Declare our View variables and assign them the Views from the layout file
        TextView factLabel = (TextView) findViewById(R.id.factTextView);
        Button showFactButton Button = (Button) findViewById(R,Id.showFactButton);
    }
}

Your pretty close, the button name is camel-case (starting with a lower case s), and the id reference needs to be R.id.showFactButton. Java is case-sensitive:

Button showFactButton = (Button) findViewById(R.id.showFactButton);
