What does it mean when Java shows that the type does not have a defined method?

edit

When Java shows that the type does not have a defined method, it means that the object or data type being referenced does not have a method with the name and parameters specified in the program code. This could be due to a typo in the method name or parameter list, the method not being implemented in the class definition or interface, or the wrong type being used to reference the method. This type of error usually results in a compiler error or runtime exception.
