COMPSCI 101 – Summer 2013
CodeWrite –– online practice activity
Due: 4:00pm, Tuesday 22
ndJanuary Worth: 1%
Introduction
Before you can successfully write and understand complex programs, you need to master basic Java syntax and develop the skills necessary to implement simple methods.
Learning to program, just like any skill, requires practice. An effective way to practice programming is to write lots of short fragments of code (each only several lines long) so that you become comfortable with the syntax of the language. At the same time, you learn the basic principles of programming and build your confidence so that you can quickly fix errors and feel ready to tackle more complex tasks.
The CodeWrite tool is designed to help you practice by presenting you with a set of short exercises. For each exercise, you need to complete the body of a single method – that is, you know the name of the method as well as the types of the inputs and output of the method, and you need to write the code to implement it.
For example, this method:
public int add(int a, int b)
is called “add” and it should return the sum of its two integer inputs. You could complete the body of this method as follows:
return a + b;
