Calculate the Total Amount of Points using Java
The challenge
Our football team finished the championship. The result of each match look like “x:y”. Results of all matches are recorded in the collection.
For example: ["3:1", "2:2", "0:1", ...]
Write a function that takes such collection and counts the points of our team in the championship. Rules for counting points for each match:
 if x>y – 3 points
 if x<y – 0 point
 if x=y – 1 point
Notes:
 there are 10 matches in the championship
 0 <= x <= 4
 0 <= y <= 4
