InetAddress.toString在SocketOutputStream.socketWrite中生成大量垃圾

Question

我正在查看写入套接字的应用程序的内存分配，我发现很多分配都是在public class MainActivity extends AppCompatActivity { private Button btn; private ImageView iv; private final int WORDNUM = 35; //转化成图片时 每行显示的字数 private final int WIDTH = 450; //设置图片的宽度 @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); iv = (ImageView) findViewById(R.id.imageView); btn = (Button) findViewById(R.id.button); btn.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { int x=5,y=10; try { TextProperty tp = new TextProperty(WORDNUM, new InputStreamReader(getResources().getAssets().open("1.txt"))); Bitmap bitmap = Bitmap.createBitmap(WIDTH, 20*tp.getHeigt(), Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(bitmap); Paint paint = new Paint(); paint.setColor(Color.WHITE); paint.setTextAlign(Paint.Align.LEFT); paint.setTextSize(20f); String [] ss = tp.getContext(); for(int i=0;i<tp.getHeigt();i++){ canvas.drawText(ss[i], x, y, paint); y=y+20; } canvas.save(Canvas.ALL_SAVE_FLAG); canvas.restore(); String path = Environment.getExternalStorageDirectory() + "/image.png"; System.out.println(path); FileOutputStream os = new FileOutputStream(new File(path)); bitmap.compress(Bitmap.CompressFormat.PNG, 100, os); //Display the image on ImageView. iv.setImageBitmap(bitmap); iv.setBackgroundColor(Color.BLUE); os.flush(); os.close(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); } SocketOutputStream.socketWrite中完成的：

有没有办法摆脱这些分配？

我使用Java 1.8.0_40在Windows上进行性能分析。

以下是来自jdk 1.8的SocketOutputStream的源代码，我没有看到可以分配这些对象的代码
