Question

项目文件：https://drive.google.com/file/d/0BxODt2IJsmR8cUQ4cVltbWFzYUk/edit?usp=sharing 这是我的运行代码

    ...........
try
soket1:=TJServerSoket.JavaClass.init((8090));
//adres:=soket1.iNetAdres.ip;
memo1.Lines.Add('Port: '+inttostr(soket1.Port));
except
  on E:Exception do memo1.Lines.Add('Port Açılamadı: '+E.Message);
end;
try
  memo1.Lines.Add('ip: '+jstringtostring((soket1.iNetAdres.Host)));
except
  on E:Exception do memo1.Lines.Add('ip bigisi alınamadı: '+E.Message);

end;
.............

............

try
  soketC:=soket1.accept;
  //o1.writeChars(stringtojstring('merhaba'));
  memo1.Lines.Add('accept' );
except
  on E:Exception do memo1.Lines.Add('accept Hata: '+E.Message);

end;

....................

try


  //i1:=soketC.getInputStream;
  memo1.Lines.Add('i1: '+inttostr(soketC.getInputStream.read) );
  //memo1.Lines.Add('i1: '+jstringtostring(soketC.getInputStream.readUTF) );
except
  on E:Exception do memo1.Lines.Add('i1 Hata: '+E.Message);
end;

try
  //o1:=TJoutStream.JavaClass.init(soketC.getOutputStream);
  //o1.writeChars(stringtojstring('merhaba') );
  soketC.getOutputStream.write(65);
  memo1.Lines.Add('o1: merhaba' );
except
  on E:Exception do memo1.Lines.Add('o1 Hata: '+E.Message);
end;

//soketC.getOutputStream.close;
//soketC.getInputStream.close;
//soketC.close;

请帮忙...... 我正在尝试“写”/“读”（输入流/输出流）到套接字但我得到错误...

这是我的坏套接字（socket'“s”）api：

需要修复;

[javaSignature('java/io/OutputStream')]
Jout=interface(jobject)
['{AC9EEC99-FF3A-46E4-AFC3-C4D3309D8C8E}']
procedure write(buffer:TJavaArray<byte>;offset,count:integer);cdecl;overload;
procedure write(buffer:TJavaArray<byte>);cdecl;overload;

写缓冲区;

编码（用于ışİçö... ...）功能;

function stringtoJbyte(metin:String):TJavaArray<byte>;
var
  buffer: TJavaArray<byte>;
  bufferByte:TArray<byte>;
  i,len:integer;
begin
  bufferByte:=TEncoding.UTF8.GetBytes(metin);
  //len:=ByteLength(metin);
  len:=length(bufferByte);
  buffer := TJavaArray<byte>.Create(len+1);
  for i := 0 to len do
        buffer.Items[i+1]:=bufferByte[i] ;
  result:=buffer;
end;

call api func;

soketC.getOutputStream.write(stringtoJbyte('kesinlikle yazar'));
