在 Java 中启动进程? [英] Starting a process in Java?

问题描述

有没有办法在 Java 中启动进程?在 .Net 中，这是通过例如:

Is there a way to start a process in Java? in .Net this is done with for example:

System.Diagnostics.Process.Start("processname");

Java 中是否有等价物，以便我可以让用户找到应用程序，然后它可以在任何操作系统上运行?

Is there an equivalent in Java so I can then let the user find the application and then it would work for any OS?

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.nio.file.Paths;

public class CmdExec {

public static void main(String args[]) {
    try {
        // enter code here

        Process p = Runtime.getRuntime().exec(
            Paths.get(System.getenv("windir"), "system32", "tree.com /A").toString()
        );

        // enter code here

        try(BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()))) {
            String line;

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

    } catch (Exception err) {
        err.printStackTrace();
    }
  }
}

您可以使用系统属性或类似方法获取本地路径.

You can get the local path using System properties or a similar approach.
