string comparer

By default, the Equals (object o) method of the Object (provided by the Base Class object) is used to compare whether two Object variables reference the same object. We must define our own object comparison methods. The IComparable and ICompare

Objective The comparison of two objects "size" is compared when the algorithm is performed to insert sort, hill sort, and merge sort. It's easy to understand the i>j of integer types, but how do we compare the size of two objects when we sort

Recommendation 10: Consider whether to implement a comparer when creating objectsThere are comparisons where objects exist, as in the world of. Net. For the simplest example, there is a salary list of 10 people in the UI. Depending on the sort needs,

In real-world projects, you often encounter sorting problems, sorting the collection for basic data type Java support Arrays.sort () and Collection.sort (), but sorting the user-defined types? Java provides us with two solutions. One: By
