在Java中,int是一种整数类型,它表示的是一个32位的有符号整数。int类型的取值范围是从 -2,147,483,648 到 2,147,483,647(即 -2^31 到 2^31-1)。这个范围是由int类型的二进制表示决定的,即在32位中可以表示的所有整数。 int的二进制表示 int类型的二进制表示使用补码(Two’s Complement)来表示有符号...
可以看到,decode 方法首先对正负号和进制符号进行识别判断,最后将剩下的纯数值部分和得到的进制数值调用静态工厂方法 valueOf(string, int) 构造 Integer 对象。 4.4. valueOf 静态方法 Integer 类支持整型和字符串型参数的工厂方法,其中字符串型的工厂方法支持指定进制,并且会先使用 parseInt 方法解析出原始 int 数值...
