## 1、金额逗号分隔 ##

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、金额大小写转化 ##
