Java exec命令提示符多于一行命令

Question

I have code like this :

Runtime rt = Runtime.getRuntime();
rt.exec("C:\\test\\MyJavaApp\\winsw\\test.exe install"); // executed
rt.exec("C:\\test\\MyJavaApp\\winsw\\test.exe start"); // not executed

How to execute the second line command too?

Answer 1

Try

Runtime rt = Runtime.getRuntime();
rt.exec("C:\\test\\MyJavaApp\\winsw\\test.exe install").waitFor();
rt.exec("C:\\test\\MyJavaApp\\winsw\\test.exe start");

because according to the javadoc this will be executed in a seperate process so the rt.exec() method immediatly returns without waiting.

public Process exec(String command) throws IOException Executes the specified string command in a separate process.
