New to Java

can any one tell me how to convert 3darray to 2darray ....
example:
double 3darray[][][] = new double[no_of_files.length][1000][2];

here this is a 3d-array representing some (assume 10) number of files each file has 1000 lines and in each line there are 2 values separated by tab...

I want to convert it to 2d-arrays so that each 2d-array represent one file...
