We are looking for a programmers who knows java to write three short java [login to view URL] programs titles are [login to view URL] Dimensional array Write a program that: Queries the user to enter two integer numbers; one representing the number of rows in a two dimensional array and the other the number of columns. Dynamically create the two dimensional array Iterate through this array and: if the row index = 0, place a '0' in the element if the column index = 0, place an 'a' in the element if both the row index and column index are even place an 'x' in the element if both the row index and column index are odd place a 'y' in the element place a 'b' in all other elements Iterate through the array and count and present to the user the number of each value ('0','a','b','x','y') present in the array.
