static String t1 = "零壹贰叁肆伍陆柒捌玖";

static char[] n = { '仟', ' ', '拾', '佰' };

static char[] n1 = {'萬','亿'};

static char end = '圆';

public static void print(String value, int pos, boolean b) {
if (pos == 0) {
System.out.print(end);
return;
}
String value2 = value.substring(1, value.length());
int printPos = value.charAt(0) - '0';
if (printPos != 0) {
if (b == true)
System.out.print(t1.charAt(0));
System.out.print(t1.charAt(printPos));
System.out.print(printPos == 0 ? "" : (n[pos % 4] == ' ' ? "": n[pos % 4]));
}
if (pos % 4 == 1 && pos > 1) {
System.out.print(n1[(pos / 4) - 1]);
print(value2, pos - 1,  false);
return;
}
print(value2, pos - 1, printPos == 0 ? true : false);
}

使用方法
print("10010202070", 11, false);
还没看懂留着慢慢看。。。
