CSC207.01 2014S, Class 06: Arrays in Java




Questions on the homework

How would you test reverseInts?

Here's one simple test.

int[] original = new int[] { 1, 2, 3, 4, 5 };
int[] expected = new int[] { 5, 4, 3, 2, 1 };

reverseInts (original);
assertArrayEquals ("onetwothreefourfive", expected, original);

But I'd probably use loops to build and fill the arrays so that I can get different size arrays.

Questions on the reading

How do I build a new array?

assertArrayEquals ("onetwothreefourfive", new int[] { 5, 4, 3, 2, 1} , original);
