我想知道System.out.printf的输出将在Android Studio中显示的位置

package com.example.kakashi.gesture1;

import android.support.v4.view.MotionEventCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.MotionEvent;

public class MainActivity extends AppCompatActivity {

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

  public void printSamples(MotionEvent event){
    int historySize = event.getHistorySize();
    int pointerCount = event.getPointerCount();
    for (int i=0;i<historySize;i++) {
      System.out.printf("At time %d",event.getHistoricalEventTime(i));
      for (int p=0;p<pointerCount;p++){
        System.out.printf("pointer %d ( %f,  %f                                                                             )",event.getPointerId(p),event.getX(p),event.getY(p));
      }
    }
  }
}
