Example text

The second and third lines of this error message include the original line of code with an arrow (caret) pointing to where the compiler got confused. The compiler errors are not always very clear, but if you pay attention to where the arrow is pointing, you’ll have a pretty good sense of where the error occurs. If you still can’t figure out the error, try looking at the error’s line number and comparing the contents of that line with similar lines in other programs. You can also ask someone else, such as an instructor or lab assistant, to examine your program.

First you transfer control to the drawBox method and execute its four statements. Then you return to main and execute its println statement. Then you transfer control a second time to drawBox and once again execute its four statements. Making these method calls is almost like copying and pasting the code of the method into the main method. println("+------+"); } This version is simpler in terms of its flow of control, but the first version avoids the redundancy of having the same println statements appear multiple times.

Then they add another piece, and another, and another. The overall program is built up slowly, piece by piece. This process is known as iterative enhancement or stepwise refinement. Iterative Enhancement The process of producing a program in stages, adding new functionality at each stage. A key feature of each iterative step is that you can test it to make sure that piece works before moving on. Now, let’s look at a construct that will allow you to iteratively enhance your Java programs to improve their structure and reduce their redundancy: static methods.
