Using println statements to trace execution

We have learned of our need to examine the intermediate results of Java statements at specific places within a program and at certain points in time. By doing so, we would likely uncover the source of a mistake in the program’s logic. Up to now, we have exhibited these results simply by inserting println statements in our code. Although this technique uses a familiar statement, we ultimately are left with a program containing extraneous statements. If we remove these statements, we ...
