Question

我尝试在java中执行一些cmd命令，我的脚本：

public void test(){
try{

Runtime rt=Runtime.getRuntime();
Process p = rt.exec("cmd /c "+"adb devices");

BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));

while((line=input.readLine())!=null){

    System.out.print(line);

}

}catch(Exception e){
    System.out.println("process failed");
    }
}

和输出结果：

run:
List of devices attached 
0160880B0401F006    device

我怎么能抓住那个结果的一部分：“0160880B0401F006”并把我的gui列入一个列表？

之前感谢

我使用a regular expression（未经测试）：

Pattern p = Pattern.compile("(\d+)\s*(.*)");
while((line=input.readLine())!=null){
    Matcher m = p.matcher(line);
    if (m.matches()) {
        String id = matcher.group(1);
        String name = matcher.group(2);
        // do whatever you want with your values here
        System.out.println("id: " + id + ", name: " + name);
    }
}

如果您在执行外部命令时遇到任何问题，还应阅读When Runtime.exec() won't。

public void test(){
        try{

            Runtime rt=Runtime.getRuntime();
            Process p = rt.exec("cmd /c "+"adb devices");

            BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
            String line=input.readLine();//discard first line
            List<String> deviceList=new ArrayList<String>();
            while((line=input.readLine())!=null){
                deviceList.add(line.split(" ")[0]);
            }
            System.out.println("Device list "+deviceList);
        }catch(Exception e){
            System.out.println("process failed");
        }
    }

catch命令输出并将其包含在列表java中
