floating-point types are, however, represented in a completely different format from their C/C++ counterparts. As in C, Java floating-point values can be represented with an exponential portion. The float type in C is used to store asignedfloating-point number value.The exact size of the flo...

java读取float java读取文件内容并输出 前言 Java I/O类分成输入和输出两部分,字节输入、输出类都继承自InputStream、OutputStream,字符输入、输出类都继承自Reader、Writer。 输入输出是以内存为参照的,将外部文件读入内存中叫做输入(Input&Read),将数据写入外部文件中叫做输出(Output&Write)。 1.字节流读写文件 首先...
