Question

我有一个工作文件重命名java工具，现在我想添加一个if条件来运行命令行命令，如果我在每个重命名的文件上选中一个框作为重命名过程的一部分。

我稍后会更改dos代码，但我找到的样本有效。我的部分问题是我的filerename是它自己的类，所以我还需要弄清楚如何组合这个类或以某种方式从我的主重命名类引用dos命令。

更新

我使用答案中的更改更新了代码，但命令行命令不起作用，它崩溃了java而没有错误。该命令可以在cmd行中运行。

import java.io.IOException;
import java.io.InputStream;

public class doscommandrun {
     public static void run() {  
         final String dosCommand = "cmd converter.exe file.doc -android -o file.txt";
            try {
                final Process process = Runtime.getRuntime().exec(
                        dosCommand + " ");
                final InputStream in = process.getInputStream();
                int ch;
                    while((ch = in.read()) != -1) {
                        System.out.print((char)ch);
                    }
                    } catch (IOException e) {
                        e.printStackTrace();
            }
        }
    }

Answer 1

您可以在名为run()的doccommandrun类中创建一个静态方法，该方法将在调用时执行main方法中当前的方法。

public class DosCommandRun 
{
   public static void run() 
   {
      //..do stuff from main
   }
}

现在，只要您想调用dos命令，就可以在代码中插入DosCommandRun.run()。

我在renametool类中的cmd之后添加/ c

我仍然遇到问题，但问题不同。

将命令行命令添加到文件重命名批处理
