How many classes can a Java program have

Yes, we can define multiple methods in a class with the same name but with different types of parameters .

There are 11 methods in Object class .

a) Methods should not have more than an average of 30 code lines (not counting line spaces and comments). b) A class should contain an average of less than 30 methods , resulting in up to 900 lines of code.13 Şub 2013

Steve McConnell in his book Code Complete recommends about 7 methods per class and no more lines in a method then can be viewed in a single screen without scrolling.

The bottom line is, do not worry about how many methods your class is. Worry about making sure your class does not take on unrelated concerns, and that you have a reasonable public interface that has easy to understand methods. Correct, but if it is a utility class, upto 10-15 is fine .29 Ağu 2011
