Answer 1

In order to use classes and methods from another jar

1) You need to include them in the classpath. In essence you add them as libraries/references.

See: Adding Classes to the JAR File's Classpath

2) The method in question needs to have the appropriate modifiers related to visibility, e.g. to not be protected or private.

See: Controlling Access to Members of a Class

--A)If the method is protected: your own jar/.class must have the same package declaration.

--B)If the method is static you can directly call it.

3) If the method is not static you need to create a new Object of the class the method is declared in, and call it.

See: Java: when to use static methods

Object whatever = new MyClass();
whatever.getOffer(paramsGoHere);
