Java TreeSet Example With Comparator : In this example, we create one TreeSet by supplying a customized Comparator. In this example, we will try to create a TreeSet of Student objects ordered in the descending order of the percentage of marks they have obtained. That means, student with hig...
ATreeSetbeing a data-structure with greater locality we can, therefore, conclude in accordance to the Principle of Locality, that we should give preference to aTreeSetif we’re short on memory and if we want to access elements that are relatively close to each other according to their natura...

In above example, we are creating TreeSet of String object. String class is having comparable interface implemented by Java library. Let’s think of a case when we need to have our own objects to be stored in Set and ordering of objects as per our rule. Below example shows Cricketers as...
