十进制转26进制（字母） dec2Alpha

 

闲话少说，直接进代码：

 

 import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.util.ArrayList;import org.apache.commons.lang.StringUtils;public class TestDemo {private static final String[] arrAlphalet = { "Z", "A", "B", "C", "D", "E", "F","J", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S","T", "U", "V", "W", "X", "Y", "Z"};public static void main(String[] args) {System.out.println(dec2Alpha(52));}public static String dec2Alpha(int decimal) {ArrayList<String> arrResult = new ArrayList<String>();int a = decimal;int b = decimal;do {b = a / 26;int c = a % 26;if(c ==0 && b == 0){arrResult.add(0,"0");}else if (c ==0 && b != 0){b = b-1;arrResult.add(0, arrAlphalet[c]);}else{arrResult.add(0, arrAlphalet[c]);}a = b;} while (a > 26);if (a!=0){arrResult.add(0, arrAlphalet[a]);}return StringUtils.join(arrResult.toArray());}}
