捕捉CMD輸出，並將其納入名錄的Java

Question

我試着做一些Java中的cmd命令，我的腳本：

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"); 
    } 
} 

，並輸出結果：

run: 
List of devices attached 
0160880B0401F006 device 

我如何能趕上部分的結果：「0160880B0401F006」並列入我的gui列表中？

Answer 1

之前，我會用a regular expression（未經測試）

感謝：

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); 
    } 
} 

你也應該閱讀When Runtime.exec() won't，萬一你碰上與執行外部命令的任何問題。

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"); 
     } 
    }
