Comp sci majors increase by 12 percent

The increase is most prevalent in introductory classes. Professor Adam Cannon, who teaches Introduction to Computer Science and Programming in Java, said that he has noticed a sizable increase in student enrollment in his class over the past few years.

“It’s increased significantly, just in the last couple of years—this year, between the fall and spring semester, somewhere between 500 and 550 students are taking the class,” he said. “The numbers have grown just in the last year or two.”

Cannon said that students are excited about learning computer science and that the increase has not had any negative effects on the class.

“The students I’m seeing in class are very motivated, which is very positive to me,” he said. “There’s not much of a difference between teaching a class of 100 and 300 in terms of delivering material—the difference is more TAs and more emails.”

Toni Ma, CC ’12 and teaching assistant for the introductory computer science course, said that she has also noticed increases in the course’s enrollment.

Learn Java programming: Introduction to Java Access Modifiers

The private sector (most restrictive) fields or methods can not be used for classes and interfaces. It can not be used for fields and methods of an interface. Fields, methods or constructors declared private are strictly controlled, which means they can not be accessed from anywhere outside the enclosing class. A standard design strategy is to make all fields private and public getter methods for them. The protected fields or methods can not be used for classes and interfaces. It can not be used for fields and methods of an interface.Fields, methods and constructors declared protected in a superclass can be accessed only by subclasses in other packages. The classes in the same package can access protected fields, methods, and constructors as well, although I'm not a member of a subclass of the class protected.
