Java 命令行使用梳理

Java 命令行代码

Java 调用命令行

Process p;
String cmds = "ipconfig /all";

try {
    // 执行命令
    p = Runtime.getRuntime().exec(cmds);
    // 获取输出流，并包装到 BufferedReader 中
    BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
    String line = null;
    while((line=br.readLine()) != null) {
        System.out.println(line);
    }
    int exitVal = p.waitFor();
    System.out.println("进程返回值：" + exitVal);
} catch (IOException | InterruptedException e) {
    e.printStackTrace();
}
