Java类转化为Jasmin汇编代码

Question

import java.util.Scanner;

public class Sample {
   public static void main(String []args){
      Scanner scan = new Scanner(System.in);
      int intAge;

      intAge = scan.nextInt();

      System.out.println("Your age is " + lol + " years old.");

      }
}

有什么办法可以将这段代码转换成jasmin汇编代码吗？我很难找到一种方法来做到这一点。答案将不胜感激。

一个人的项目，非常古​​老(最后更新 2009 年)，
但根据wikipedia jasmin 的最后一次更新是 2010 年。

我用一个简单的文件测试了它，它工作正常。

编辑:我正在展示示例的用法和输出，以保证答案的完整性。 (上面代码中的lol被替换为intAge)
