以下算法可以转36进制以下的任何进制。

import java.math.BigInteger;

public class Test {
    public static String baseString(int num, int base) {
        String str = "", digit = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
        if (num == 0) {
            return "";
        } else {
            str = baseString(num / base, base);
            return str + digit.charAt(num % base);
        }
    }

    public static String baseString(BigInteger num, int base) {
        String str = "", digit = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
        if (num.shortValue() == 0) {
            return "";
        } else {
            BigInteger valueOf = BigInteger.valueOf(base);
            str = baseString(num.divide(valueOf), base);
            return str + digit.charAt(num.mod(valueOf).shortValue());
        }
    }

    public static void main(String[] args) {
        System.out.println(baseString(1295, 36));
        BigInteger big = new BigInteger("28");
        System.out.println(baseString(big, 14));
    }
}

转14不是16？
16进制的话
import java.util.Scanner;
public class Test {
public static void main(String[] args) {

Scanner sc = new Scanner(System.in);
System.out.println("请出入一个十进制数");
int x = sc.nextInt();
System.out.println(x+"的十六进制结果是："+Integer.toHexString(x));
}
}
