java - How to separate each digit in a number? -

i working on homework assignments making program allows user enter in low , high value range , program suppose find numbers sum of cubed digits (ie 153 = 1^3 + 5^3 + 3^3) , loop has used. i'm stuck on figuring out how go this, need separate each digit of number take each digit cube it, add them check see if equals value if not repeat that's far have gotten planning wise appreciated.

you can isolate digits using % or mod tool. then, go next digit, divide number 10, making last digit go away. process can used go through digits of number.
