 *实际上字节流在操作时本身不会用到缓冲区（内存），是文件本身直接操作的，而字符流在操作时使用了缓冲区，通过缓冲区再操作文件。 
 * 
 *字符流和字节流是根据处理数据的不同来区分的。字节流按照8位传输，字符流按照16位传输 
 *由于字符流使用Unicode字符集，支持多国文字，因此若流要跨越多种平台传输，应使用字符流。 
 *=============================================================================================================== 
 *char型是字符型,占2个字节,默认数值'\u0000',取值范围'\u0000'~'\uffff' 
 *byte是字节型,占1个字节,默认数值0,取值范围-128～127 
 *boolean 无符号 8  位  
 *byte  无符号,8  位  
 *char  无符号,16 位 
 *short 有符号,16 位 
 *int \ 有符号,32 位 
 *long 有符号,64 位  
 *float  32 位  
 *double  64 位 
 *=============================================================================================================== 
 *字节流输出--->>程序-->>字节流---->文件(直接操作文件) 
 * 
 *字符流输出--->>程序-->>字符流---->>缓存--->>文件(数据线放在缓存,之后再从缓存写入文件)
