Is it possible to have a multi dimensional array of double type, with size
[10][50][120][120] - which holds nearly 10MBits of data ?
Is it possible to transfer this amount to applet, from servlet?

You store 10*50*120*120 * 8 byte = 57.6 MByte of data. This would also be the memory footprint of a one-dimensional array of doubles.Quote:

This is because in addition to the actual doubles also references to arrays are stored internally. You can approximate this as 10*50*120 * 4 byte = 0.24 MByte of references which should be added.
So you have lets say 60 MByte of data. This is nothing for a computer today which usually has several GByte of memory.
60 MByte corresponds roughly to the Java SDK download which usually takes about a minute or two (over my 10 Mbit/s connection). So this amount of data certainly can be transfered but whether the time it takes is feasible depends I guess on how much your users cherish the goodies they're waiting for.
