check if two subsets of integers are equal using equals method
- by MAS
I have this java method in class called IntArray. The class has methods to add integers to a set or remove integers from a set,check size of a set, and check if 2 sets are equal. the 2 sets are created using 2 different objects of type IntArray in main, lets say object A and B. equals method supposed to check if two sets of integers are equal. for example set A = {1,2,3} and B = {1,2,3,4}. The method still return true even though one set is a subset of the other set. What exactly I am doing wrong? Thanks.
//part of the code in main
IntArray A = new IntArray();
IntArray B = new IntArray();
if(A.equals(B))
System.out.println("A and B are equal");
//equals method in IntArray class
public boolean equals(Object b)
{
if (b instanceof IntArray)
{
IntArray A = (IntArray) b;
for (int i = 0; i < data.length; i++)
if (countOccurrences(data[i]) != A.countOccurrences(data[i]))
return false;
return true;
}
else return false;
}
