NeighborNumbers.java

/*Given two strings as input, write a program to find which numbers from the first string are present in the second string. Print the result as a string containing the
matched numbers in ascending order.
For example:
Input:
"12, 13, 15, 19, 212, 556, 2146"
"13, 44, 432, 12, 788, 246, 2146, 46"
Output: "12, 13, 2146"
