java - Converting a Base Ten Number to Any Number -

there several similar threads around here pose question mine unable find solution works relatively simply. wondering if guys had ideas.

---

i have code take base ten number , convert number in base 1 11. it's when start getting things hexadecimal format struggle because need letters in addition numbers base. i'm sure solution pretty simple escaping me. appreciated.

import static java.lang.system.*;  public class tentoany {     private int base10;     private int newbase;       public tentoany(int ten, int base)     {         base10 = ten;         newbase = base;     }      public void setnums(int ten, int base)     {              base10 = ten;          newbase = base;     }      public string getnewnum()     {         string newnum="";         int original = base10;          while(original > 0)         {             newnum = original%newbase + newnum;             original = original/newbase;         }         return newnum;     }      public string tostring()     {        string complete = base10 + " base 10 " + getnewnum() + " in base " + newbase;         return complete;     } } 

there number of possible solutions. i'm including instructional value, not because think it's better other answer. replace:

newnum = original%newbase + newnum; 

with

int digitvalue = original % newbase; char digit = (digitvalue < 10) ? ('0' + digitvalue) : ('a' + (digitvalue - 10)); newnum = digit + newnum;
