Apply Quicksort recursively to right subarray.

The Java API contains several overloaded sort methods for sorting primitive type values and objects in the java.util.Arrays and java.util.Collections class. For simplicity, this section assumes: data to be …

Bubble sort is one of the first algorithms for sorting that people come up with. If we want to sort the array from smallest to largest, we can simply go through it, look at the elements pairwise and if the first in …

Note: Collections is a Java public class and Comparator is a public interface. Comparators can be passed to a sort method (such as Collections.sort()) to allow precise control over the sort order.

Two slightly better O(n2) algorithms are Selection Sort and Insertion Sort.

Normally, when invoking generic methods, you donʼt have to tell Java explicitly what the type of the arguments is. Instead, the type is automatically inferred from the compile-time types of the arguments.

This chapter discusses several standard algorithms for sorting, i.e., putting a number of values in order. It also discusses the binary search algorithm for finding a particular value quickly in an array of …
