如何在unixshell中运行命令，然后从/到java应用程序获取输出

我知道如何从java应用程序执行shell命令。应该是这样的：

String command = "java -version";
Process proc = null;
try {
  proc = Runtime.getRuntime().exec(command);
}
catch (IOException e) {
System.out.print(e);
}

我希望将此命令的输出返回到我的java应用程序，而不将输出打印到某个临时文件，然后从我的应用程序读取该文件。这可能吗？

您需要使用ProcessBuilder

Process process = new ProcessBuilder(
"C:\\PathToExe\\exe.exe","param1","param2").start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;

System.out.printf("Output of running %s is:", Arrays.toString(args));

while ((line = br.readLine()) != null) {
  System.out.println(line);
}

在java中的stackoverflow Execute external program上已经找到的代码请注意processbuilder与解决方案没有任何关系，只是在process类中使用getinputstream方法。请注意processbuilder与解决方案没有任何关系，这只是在流程类中使用getinputstream方法。请注意，processbuilder与解决方案无关，而解决方案只是在流程类中使用getinputstream方法。请注意，processbuilder与解决方案无关，而解决方案只是在流程类中使用getinputstream方法。
