金額大小寫轉化_金額工具類

1、金額逗號分隔

public class DecimalUtils {

    public static final DecimalFormat FORMAT = new DecimalFormat("#,##0.00");

    /**
     * @param decimal  71015000009826
     * @return 71,015,000,009,826.00
     */
    public static String format(BigDecimal decimal ,DecimalFormat format) {
        return format.format(decimal);
    }



}

2、金額大小寫轉化

import java.math.BigDecimal;

    private static final String CN_NEGATIVE = "負";
    private static final String CN_FULL = "整";
    private static final String CN_ZEOR_FULL = "零元整";

     * @return
