Java 十进制转十六进制(右移符号的完美运用)
1). 源码
1 //十进制数转十六进制 2 import java.util.Scanner; 3 4 public class Test01{ 5 public static void main(String[] args){ 6 while(true) 7 { 8 System.out.print("Please input an integer:"); 9 10 Scanner s = new Scanner(System.in); 11 int n = s.nextInt(); 12 13 DataConvert DC = new DataConvert(); 14 DC.Decimal_To_Hexadecimal(n); 15 } 16 17 } 18 } 19 20 //使用右移运算符">>" 21 class DataConvert{ 22 public void Decimal_To_Hexadecimal(long n){ 23 String[] k = new String[8]; 24 int icount = 0; 25 26 while(icount <= 7){ 27 k[icount++] = ((n&15) > 9)?(char)((n&15) - 10 + 'a') + "":(n&15) + ""; 28 n = n>>4; 29 } 30 31 icount -= 1; 32 33 while(icount >= 0){ 34 System.out.print(k[icount--]); 35 } 36 System.out.println(""); 37 } 38 };
2). 分析:用100做实验(即:01100100)
总结:100的十六进制是“64”
