Sorting is a process of arranging the elements of an array in a defined manner which may be either in ascending order or in descending order. This thesis focuses only on testing the effectiveness of five different sorting techniques, namely bubble sort, insertion sort, selection sort, merge sort and quick on.
Tree is one of the most powerful and advanced data structures. The importance of sorting lies in the fact that data searching can be optimized to a very high level, if data is stored in a sorted manner. The main idea is to reduce the space and time complexities of different tasks. Sorting algorithm specifies the way to arrange data in a particular order. These are similar to records, where the result or manipulation of data is reflected for the whole table. For example, we can store a list of items having the same data type using the array data structure. Sorting algorithms in data structure for application.

Sorting refers to ordering data in an increasing or decreasing fashion according to some linear relationship among the data items. Java sorting algorithms java sorting algorithm programs. For example for integer data type 10 is valid data while a is not.
This type of data structure follows the sorted order of insertion, deletion and modification of data items.
