You don't convert chars to integers at all; chars always are integers (see this Java™ Language Specification section). You convert a character to an integer when you say char c = '5' and when you print it out System.out.println(c); you are converting an integer to a character. ...
*为了对基本数据类型进行更多的操作,更方便的操作,Java就针对每一种基本数据类型提供了对应的类类型。包装类类型。* byte Byte * short Short * int Integer * long Long * float Float * double Double * char Character * boolean Boolean * *用于基本数据类型与字符串之间的转换。*/publicclassIntegerDemo {...
