java 调用执行.exe文件，输入输出重定向

[D385675753]

Process proc =rt.exec("gcc C:\\test.c -o C:\\test");
proc=rt.exec("C:\\test.exe");
test.exe要输入一个数，然后输出这个数。
这个数要从文件里输入。怎么弄？然后把输出地结果，保存到.txt文件夹里。大概就这样子的。

BufferedReader br = new BufferedReader(new InputStreamReader(proc.getInputStream()));//这里是输出
BufferedWriter bw=new BufferedWriter(new OutputStreamWrite(proc.getOutputStream()));
File file = new File("C:\\test1.txt");
BufferedReader reader = new BufferedReader(new FileReader(file));
String tempString = null;
int line = 1; // 一次读入一行，直到读入null为文件结束
while ((tempString = reader.readLine()) != null)
{
System.out.println("line " + line + ": " + tempString); // 显示行号
line++;
bw.write("\n"+tempString+"\n");
bw.flush();
}

		try {

			// 输入文件
			File fileInput = new File("C:\\input.txt");
			BufferedReader readerInput = new BufferedReader(new FileReader(fileInput));

			// 输出文件
			PrintWriter writerOutput = new PrintWriter(new BufferedWriter(new FileWriter("C:\\output.txt", true)));

			Process cmdProcess = null;
			BufferedReader bufferedReaderCmdRes = null;
			
			String strOutputMsg;
			String strRead;
			String strCommand;

			while ((strRead = readerInput.readLine()) != null) {
				strCommand = "C:\\test.exe " + strRead;
				cmdProcess = Runtime.getRuntime().exec(strCommand);
				
				bufferedReaderCmdRes = new BufferedReader(new InputStreamReader(cmdProcess.getInputStream()));
				while ((strOutputMsg = bufferedReaderCmdRes.readLine()) != null) {
					writerOutput.write(strOutputMsg);
					writerOutput.flush();
				}
				cmdProcess.waitFor();
			}
			readerInput.close();
			writerOutput.close();
		} catch (Exception e) {
			System.out.println(e);
		}

strCommand = "C:\\test.exe " + strRead;
不能直接带参数的啊。我这试了下，不行。
