Implement a class, called Combination, to store three integer values (ints). 1. declare the necessary instance variables to store the three integer values; 2. create a constructor, public Combination(int first, int second, int third), to initialize the values of this object. constructor, given the following: Combination c1,c2,c3; c1= new Combination (1,2,3); c2= new Combination (1,2,3) c3= new Combination (3,2,1) then c1.equals(c2) is true but c1.equals(c3) is false; 4. finally, implement the method public String toString(), to return a String representation of this object, where the first, second and third values are concatenated and separated by ":" symbols. E.g. Combination c1; c1 = new Combination (1,2,3); System.out.println(c1); displays "1:2:3". The interface of the class Combination consists therefore of its constructor, the method equals and the method toString. Note: Simpler code is better and it is worthwhile spending time cleaning up code even if it was already working
