This is a java lab question. Please help me to get the answer ASAP.

Implement a class, called Combination, to store four integer values (ints) Declare the necessary instance variables to store the four integer values Create a constructor, public Combination (int first, int second, int third int fourth), to initialize the values of this object Implement the instance method public boolean equals (Combination other), such that equals return true if other contains the same values, in the same order, as this Combination; the order is defined by the order of the parameters of the constructor, given the following: Finally, implement the method public String toString(), to return a String representation of this object, where the first, second, third and fourth values are concatenated and separated by symbols. E.g. The interface of the class Combination consists therefore of its constructor, the method equals and the method toString. Ideally, the input data should be validated. In particular, all the values should be in the range 1 to 10. However, since we do not yet have the tools to handle exceptional situations, we will assume (for now) that all the input data are valid
