前言

  我的开源路声明:[传送门]

  为了实现自己的目标,不幸自己就选择在博客园上练习自己英语。希望英语多,中文少,然后渐渐地成为习惯。加油!

  实现十进制转(2到16)进制原理及安卓

 

The Principle (原理)

  ①the Stack ADT (栈知识)

    小朽是活学活用,栈知识复习[传送门]

  ②the Short division (短除法)

    

  Start...

              the jar struckture

   

  ALStack.java

package sedion.jeffli.action; import java.util.ArrayList;import java.util.Stack; /** * My Open-Source road * @author Jeff Li * * @param <T> */ public class ALStack<T> extends Stack<T> { /** * */ private static final long serialVersionUID = -1261738006146239371L; private ArrayList<T> stackList = null; //create an empty stack by creating an empty ArrayList public ALStack(){ stackList = new ArrayList<T>(); } }

  

  BaseStr.java

      

package sedion.jeffli.action; import java.util.Scanner; public class BaseStr { public static void main(String[] args) { int num , b; Scanner keyIn = new Scanner(System.in); System.out.print("Enter a decimal number: "); num = keyIn.nextInt(); System.out.print("Enter a base (2 to 16): "); b = keyIn.nextInt(); System.out.print(" "+num+" base "+b+" is "+baseString(num, b)); } //the short division principle public static String baseString(int num,int b){ //digitChar.charAt(digit) is the character that represents the digit , 0 <= digit <= 15 String digitChar = "0123456789ABCDEF",numStr = ""; //stack holds the base-b digits of num ALStack<Character> stk = new ALStack<Character>(); do{ //push right-most digit on the stack stk.push(digitChar.charAt(num % b)); //remove right-most digit form num num /= b; }while(num != 0); while(!stk.isEmpty()){ //pop stack and add digit on top of stack to numStr numStr += stk.pop().charValue(); } return numStr; } }

 

    *核心

      短除法原理,短除就是在除法中写除数的地方写两个数共有的质因数,然后落下两个数被公有质因数整除的商,之后再除,以此类推,直到结果互质为止

 

                

 

    实现demo,its a bit easy ,right?              //push right-most digit on the stack stk.push(digitChar.charAt(num % b)); //remove right-most digit form num num /= b;
