为什么我不断收到Java错误：错误：可以找到或加载类Dint？

您能否花点时间来阅读本文，因为我没有Java经验，所以需要帮助。如果您能告诉我该错误的原因以及解决方法，将不胜感激！提前度过美好的一天。我正在编译一个Dint版本，当我编译它时

javac *.java
jar -cvmf manifest.txt Dint.jar *.class
del *.class
echo Finished!
pause >nil

编译没有向我抛出任何错误，但是为什么我会得到错误错误：找不到或加载类Dint after I open it with:

@echo off
cls
java -jar Dint.jar
pause

manifest.txt：

感谢您的阅读，我真的需要帮助，因为我对Java没有太多的经验。
