Question

in line“int k = 2 * AudioTrack.getMinBufferSize（paramInt1，i，j）;”给我标题错误，我打字不知道为什么给我这个错误，有什么不对？（我的ide = eclipse）

public class EmuMedia
{
private static SurfaceHolder holder;

任何人都可以帮助我吗？特别感谢您的帮助

Answer 1

您可以在任意语句上添加标签。因此int k; label: k = 0;是完全合法的java。但是label: int k = 0;不能编译，因为声明不算作语句。但是，你真的应该只在循环语句中使用标签，即使只是在极少数情况下（例如突破嵌套循环）。你当然不应该使用标签来解决goto不受支持的事实。
