The twoDArray in your case is just an array of size 10 with each slot referring to a integer array i.e. two dimensional arrays in Java are just an array of arrays. Hence you can either use twoDArray[3] = oneDArray; or System.arraycopy if you don't want modifications in the original oneDArray to be reflected in twoDArray. Also read this.

I don't accept change; I don't deserve to live.
