Java basic knowledge, grammar, basic data types and other aspects are not very grasp, often in some very basic problems toss a good time, recently in the implementation of the "Hundred Yards" program, so dedicated to write a blog to record the daily programming process encountered some weak knowledge points, accumulate each, to fill their weaknesses.　1.Spinner setting default valuesAfter setting the data adapter to spinner, the system defaults to the

at this time is:C. Finally, assign the object you just created to the reference variable. 3. Summary of construction methods(1) There is at least one constructor in every class in Java, and if we do not define a constructor in a class, then the system automatically generates a default constructor for that class, which has no parameters and no code in its method body, that is, nothing. (2) Construction meth

parameter?(1)Passing a reference to a function has the same effect as passing a pointer.. In this case, the parameter of the called function becomes an actual parameter variable or an alias of the object in the original main function, therefore, the operations on the parameters in the called function are the operations on the corresponding target object (in the main function.(2)When a parameter passing a f
