2.1 Number 抽象类 Number 是 BigDecimal、BigInteger、Byte、Double、Float、Integer、Long 和 Short 类的超类,此外JDK1.8还扩 展出了一些累加器(扩展抽象类Striped64,并基于此类实现累加器)。 Number定义了一系列将表示的数值转换基本数值类型的方法,具体类型如下: 整数类型: byte(8位,用于表示最小数据单位;数值范围...
Integer继承了抽象类Number,并实现了它的下列方法:byteValue()shortValue()intValue()longValue()floatValue()doubleValue(),将int转换为其他基本类型的值,实现方法都是强转。 Integer还实现了Comparable接口,因此也具备了比较对象大小的能力,其compareTo()方法具体实现如下: 代码语言:javascript 代码运行次数:0 运行 A...

In addition, this class provides several methods for converting an int to a String and a String to an int, as well as other constants and methods useful when dealing with an int. Number 接口 其继承了Number接口,能够转换成 int, long, float, double, byte, short等类型。 继承了Number接口的类...
NSInteger是基础类型,但是NSNumber是一个类。如果想要在NSMutableArray里存储一个数值,直接用NSInteger是不行的,比如在一个NSMutableArray里面这样用: NSMutableArray *array = [[NSMutableArray alloc]init]; [array addObject:[NSNumber numberWithInt:88]]; ...
