You can not call any method from terminal or cmd of any class.
您不能从任何类的终端或 cmd 调用任何方法。
You can execute class through terminal.
您可以通过终端执行类。
If your jaris executable try: java -jar "Name of your Jar"
如果您jar是可执行的，请尝试： java -jar "Name of your Jar"
Or set the class path of your jar: java -classpath path-to-jar <package>.<classname>
或者设置 jar 的类路径： java -classpath path-to-jar <package>.<classname>

I need to call a method from it.
我需要从中调用一个方法。
This is not very specific statement. if you are interested to call main method of your Main class then you can do
这不是很具体的说法。如果您有兴趣调用 Main 类的 main 方法，那么您可以这样做
java -jar path/to/yourjar/yourJar.jar
if you want to call a method from this class from another class then you need to add this jar into your classpath and then you can access other methods. but since you wrote from terminal I assume the first approach fits for you
如果你想从另一个类调用这个类的方法，那么你需要将这个 jar 添加到你的类路径中，然后你就可以访问其他方法。但既然你是从终端写的，我认为第一种方法适合你
回答by Ajmal Muhammad P
you can call a specific method from a jar file if and only if the developer programmed the file to call it from outside. You can use a jar explorer to fine the details of each class inside a jar file
当且仅当开发人员对该文件进行编程以从外部调用它时，您才能从 jar 文件调用特定方法。您可以使用 jar 资源管理器来细化 jar 文件中每个类的详细信息
