Join Peggy Fisher for an in-depth discussion in this video Sorting arrays, part of Up and Running with Java.
- It is often necessary to have an array…in sorted order, especially if you want…to later use it with a binary search…on the array, which requires the array…to be sorted first.…There are many different algorithms…available for sorting.…In this segment we're going to go…through a few of the most popular.…Let's start with a selection sort.…The selection sort starts with the first value…in the array and then compares it…to the remaining items, searching for the smallest…if we're trying to sort in ascending order,…or searching for the largest if we're…trying to sort in descending order value in the list.…
Once it is located, it swaps the two values.…It continues this process, looking for the next…value until the entire list is sorted.…The selection sort requires a nested loop.…We'll take a look at the two nested loops…when we look at the program source code.…The number of times the sort passes…through the array is always one less…than the number of items in the array.…In the selection sort the inner loop…finds the next smallest or largest value,…
