I'm trying to create a 5*3 array table that is generated with non-repeating values, but I cant seem to shuffle all the arrays efficiently without repeating values. Please help.

First of all welcome to the Javaranch!

Something like:

Create the array.
Fill the array with number 1 through 15
start loop
get random x
get random y
get random x2
get random y2
swap(array[x][y], array[x2][y2])
end loop
