My java is horrible, so I'm not providing the actual code here, as it would probably be wrong. I've done this exact thing in SQL before though, so I know it works...

2. Begin a loop with variable Z going from 1 to X where X is the number elements in your array (here called AR)
3. In the loop, set AR(Z) to a random number between 1 and Y-X+Z
4. Subtract the new value from Y, so Y = Y - AR(Z)
5. End loop : back to step 2, advancing Z by 1
