在命令行/批处理文件/python脚本中运行java main class

Question

I have a java class which is to be made into a tool so that I can give the input to the class as parameters and then produce the output in the command line, I have written the code in IntelliJ and want the code to be portable so它可以通过单击按钮立即使用。 我在创建 bat 文件或 python 脚本方面几乎没有经验。

package ase.ATool;
import java.io.*;
import java.util.*;
import java.util.regex.*;

public class AnaliT {
    public static void main(String[] args) {
        File file = null;
        File dir = new File(args[0]);
        File[] directoryListing = dir.listFiles();

        StringBuffer componentString = new StringBuffer(100);
        if (directoryListing != null) {
            for (File child : directoryListing) {
                float complexity = 0, noOfMethods = 0;
                System.out.println(child.getPath() + " ");
                String currentLine;
                BufferedReader bufferedReader = null;
                try {
                    bufferedReader = new BufferedReader(new FileReader(child.getPath()));
                    System.out.println(bufferedReader);
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }
}

我想将上面的代码转换成一个工具，这样我就可以从命令行、批处理文件或 python 文件调用这个主 function。

You could compile and run the java file from python by checking out the subprocess module: https://docs.python.org/3/library/subprocess.html

您还可以使用系统模块运行 java 代码： 使用 os.system() 在 python 中运行 java 文件

If you want to invoke Java code from python, take a look here: Calling Java from Python Here it is recommended you use Py4J .

在这里您可以找到从 a.bat 文件运行 Java Class 的示例： 如何通过.bat 文件运行 java 应用程序

As mentioned in a comment you can also compile the file with java using java target.java and then run it with java target in the same directory
