Question

金额转换，阿拉伯数字转换成中国传统形式。 写个测试方法！！急！！只要打印那一部分！

public class NumberConvertor {
static final char NUMBER_CHAR[] = new char[] { '零', '壹', '贰', '叁', '肆',
'伍', '陆', '柒', '捌', '玖' };
static final char UNIT_CHAR[] = new char[] { '拾', '佰', '仟', '万', '拾', '佰',
'仟', '亿', '拾', '佰', '仟' };

public String convert(int number) {
int remainingNumber = number;
StringBuffer sb = new StringBuffer();
int pos = 0;
int preDigit = -1;
while (remainingNumber > 0) {
int digit = remainingNumber % 10;
if (isUnitToPrint(digit, preDigit, pos)) {
sb.insert(0, UNIT_CHAR[pos - 1]);
}
if (isDigitToPrint(digit, preDigit, pos))
sb.insert(0, NUMBER_CHAR[digit]);
pos++;
preDigit = digit;
remainingNumber = remainingNumber / 10;
}
return sb.toString();
}

private boolean isDigitToPrint(int digit, int preDigit, int pos) {
//个,万,亿的零不输出
if (digit == 0 && (pos == 0 || pos == 4 || pos == 8)) {
return false;
}
//前后相邻,高位零不输出
if (digit == 0 && preDigit == 0) {
return false;
}
return true;
}

private boolean isUnitToPrint(int digit, int preDigit, int pos) {
//个位没有单位
if (pos == 0) {
return false;
}
//万,亿必须输出
if (pos == 5 || pos == 9) {
return true;
}
//零后不输出单位
if (digit == 0) {
return false;
}
return true;
}

}
