In Java, the Collection framework provides a set of interfaces and classes to handle groups of objects. The framework offers various operations to manipulate and perform calculations on collections, such as finding the sum of elements in a collection. This article will discuss how to calculate the...

If you add more methods that also change the contents and calculate the sum of the elements of the List then you'll find that this workaround is not the ideal one since you'll have to remember to reset the humanCount field in those methods as well. That would result in code duplication...
Given a non-empty array containing only positive integers, find if the array can be partitioned into two subsets such that the sum of elements in both subsets is equal. Note: Each of the array element will not exceed 100. The array size will not exceed 200. ...
