liudr Full Member Offline Posts: 175	Silly me, how to do this? Create 2-d object arrays Dec 7th, 2009, 9:08am   I'm having trouble creating a 2-D array of objects. I know 1-D object Array1[]={}; Array1=(object)append(Array1,new object(init)); How do I do it in 2-D? Two cases, say if I know the dimension is Aray2[4][3] in case one, and say if I don't know the dimension till at runtime in case two? Thanks a lot.

Re: Silly me, how to do this? Create 2-d object arrays Reply #1 - Dec 7th, 2009, 9:19am   I would just avoid using "dynamic" 2D arrays... You need them to do what? In Java, 2D arrays are actually arrays of arrays, meaning you can actually have jagged arrays (different length on each row). Example: Code: int[][] ar = new int[5][]; ar[0] = new int[1]; ar[1] = new int[2]; ar[2] = new int[3]; ar[3] = new int[4]; ar[4] = new int[5]; ar[2][2] = 42; println(ar[2]); int[][] arr = new int[4][2]; arr[2][1] = 111; println(arr[2]);
