Decimal to Base Conversion The following example shows how to convert a number in Decimal system to any other base system and vice versa.
Here we considered a system with base 32.
package com.bethecoder.tutorials.core.integer; public class Integer2OtherBase { /** * @param args */ public static void main ( String [] args ) { int num = 121 ; int radix = 32 ; //where radix >=2 (Character.MIN_RADIX) && // radix <= 36 (Character.MAX_RADIX) String str = Integer.toString ( num, radix ) ; System.out.println ( num + "(decimal) in base32 : " + str ) ; num = Integer.parseInt ( str, radix ) ; System.out.println ( str + "(base32) in decimal : " + num ) ; //3p = 3*32^1 + p * 32^0 //3p = 3*32 + 25 * 1 //3p = 96 + 25 * 1 //3p = 121 } }
121(decimal) in base32 : 3p
3p(base32) in decimal : 121
