十进制数字→十六进制字符

import java.util.Scanner;

public class Case10_NumberTo0xchar{
	public static void main(String[] args) {
		
		Scanner in = new Scanner(System.in);
		System.out.print("输入0~15之间的一个整数：");
		int a = in.nextInt();
		char result;
		
		if(a>9)
			result = (char)('A'+(a - 10));
		else
			result = (char)('0'+ a);
		System.out.println("转为十六进制为："+ result);
