java - 如何使用一些参数从 Java 调用 .exe 文件

Question

我需要调用 cowsay.exe(这个程序使用符号 画动物)并执行命令:cowsay“你好”。如何将“hello”作为参数传递？

public class cowsay {
    public static void main(String[] args) throws IOException {
        Process process = new ProcessBuilder("D:\\cowsay.exe","cowsay Hello").start();
        InputStream is = process.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        String line;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }
    }

您使用 java.lang.Runtime 类:

public class cowsay {
    public static void main(String[] args) throws IOException {
        Process process = 
                Runtime.getRuntime().exec("cowsay hello");
        InputStream is = process.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        String line;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }
    }
}
