Using Java to design and implement the class PascalTriangle that will generate a Pascal Triangle from a given number of rows. Represent each row in a triangle as a list and the entire triangle as a list of these lists. Please implement the class ArrayList for these lists. Please do not use the binomial coeffiient formula { C(n,k)= n! / (k!*(n-k)!) to create the triangle. The triangle has to be generate using in this way: each row of the triangle begins and ends with 1, value at (x,y) equals to sum of value at (x-1, y-1) & (x-1,y), whereas x is the row number and y is the columm.
