本文探讨了Java中数值类型的平台独立性，并介绍了浮点数类型及其精度特点。此外，文章对比了C/C++与Java在整型使用上的区别，并讨论了十六进制与八进制在编程中的应用。
1. alleviate:减轻、缓解
This allevates a major pain for the programmer who wants to move software from one platform to another,
or even between operating systems on the same platform.
2. in contrast:相反
In contrast, C and C++ programs use the most efficient integer type for each processor.
3. suffix：后缀
prefix：前缀
4. hexadecimal：十六进制
octal：八进制
5. we recommend against the use of octal constants.
6. In Java,the sizes of all numeric types are platform independent.

7. Note that Java does not have any unsigned types.
1. The floating-point types denote numbers with fractional parts.
2. approximately: 大约、近似
3. precision: 精度
The name double refers to the fact that these numbers have twice the precision of the float type.
