方法名:wrap

Numbers.wrap介绍

[英]Wraps the given floating-point value in a Number of the specified class. The given type shall be one of Byte, Short, Integer, Long, Float, Double, BigInteger and BigDecimal classes. Furthermore, the given value shall be convertible to the given class without precision lost, otherwise an IllegalArgumentException will be thrown.
[中]将给定的浮点值包装在指定类的数字中。给定的类型应为字节、短、整数、长、浮点、双精度、大整数和大十进制类之一。此外,给定的值应可转换为给定的类,而不会丢失精度,否则将抛出IllegalArgumentException。
