“12345”按照十进制转成12345的方法其实就是以下方式:((1*10)+2)*10)+3)*10+4)*10+5具体的如何依次取出“12345”中的每一个字符并将起转成不同进制int类型则是Character.digit方法实现的,这里就不深入讲解了。 总结 上面列举了很多能够将String转成Integer的方法。那么他们之间有哪些区别,又该如何选择呢?
char --- Character【特殊 常用】 boolean---Boolean 包装类的一些功能原理上是相似的,只需要学习一种典型类,其他的类就可以借鉴学习了 包装类对象赋值的时候可以随便赋值?不可以,赋值的时候数据严格的遵守基本数据类型对应的数据范围进行赋值 Byte 的对象赋值的时候只能赋值 -128 到 127 之间的数据...

itoa() is a function in C that converts an integer to a null-terminated string. It can handle both positive and negative numbers. The resulting string is null-terminated, meaning it ends with a null character ('\0') to mark the string’s termination. This ensures compatibility with C st...
