title: Convert number in one base to another base in Java without using libraries
body: <p>This is not a homework problem, I am too old to get home works :) </p>
  
  <p>So, ideally I am trying to convert a number in a given base to another given base. </p>
  
  <p>Can someone please share the logic, then probably I can write the code myself. Not able to find anything online surprisingly. </p>
