![]() ![]() There are also lots of solid jokes and lasting insights. There’s some technical language along with a few pretty basic mathematical concepts. ![]() This issue comprises a single story devoted to demystifying code and the culture of the people who make it. Those who don’t understand will be left behind. Now that software lives in our pockets, runs our cars and homes, and dominates our waking lives, ignorance is no longer acceptable. Which means that people have been faking their way through meetings about software, and the code that builds it, for generations. ** Doubles the first 5 elements of the array */įor (int i = 0 i < values.Software has been around since the 1940s. What will the following code print out? Can you write a similar method called tripleFirstFour() that triples the first 4 elements of the array? Make sure you test it in main. ![]() It is created in the constructor and changed or accessed by the methods. ![]() Notice that it uses a complex conditional ( &) on line 14 to make sure that the loop doesn’t go beyond the length of the array, because if you had an array that had less than 5 elements, you wouldn’t want the code to try to double the 5th element which doesn’t exist! Notice that in this code, the array is a private instance variable of the class ArrayWorker. The following code doubles the first five elements in an array. You can loop through just some of the elements of an array using a for loop. You don’t have to loop through all of the elements of an array. You must start at the length of the array minus one.
