Question

I have a arraylist and it contains a 100 employee object and each object contains “Name” and “Salary”. We need to find the Max salaried employeee from the Object .Please let me know what is the way .

I thought of implementing compareTo and equals Method is it right , and also using Collections.sort Is it the right way or is there any other way

Answer 1

If the language is Java, then either implement the Comparable interface (just compareTo–no need for equals) for the objects in the array list and call Collections.sort(arraylist), or else write a Comparator and call Collections.sort(arraylist, comparator). The latter is more flexible, as it doesn’t require your objects to always be sorted by salary.
