Please show me an example of a situation where it is necessary to use double or triple indirection and why double or triple indirection is the right solution in this situation.

This is not a homework assignment. I have an M.Sc. IT degree and I am a SUN certified java programmer. I just need to brush up on indirection. Thanks.

The most common application of multiple indirection is dynamically sizeable arrays.  Double indirection appears in 2-D dynamic arrays; triple indirection, in 3-D dynamic arrays.  

Assignment to an array element must occur through the references that support the multidimensional array structure.

Moreover, simple assignment is not possible in a method that inserts a value into a linked list.  The nodes of a linked list are usually unnamed, dynamically allocated  instances in the heap.  Simple assignment to a variable is impossible since a variable name does not exist. The insertion function gets only a reference to the node where the value is to be stored.
