如何构建 Apache Commons Lang Range<Integer>目的?
如何创建 Apache Commons Lang 3.1 Range
对象?
JavaDocs 说:
<块引用>从最小值到最大值的不可变对象范围."
<块引用>
"这些对象要么是 Comparable 的实现,要么你需要提供一个 Comparator."
但是当我尝试时:
范围<整数>range = new Range<整数>(100, 200);
我在我的 IDE 中收到一个错误,指出所需的参数是整数、整数、比较器.
尽管 Integer
实现了 Comparable
接口,因此我不需要额外的比较器.
谁能给我一个如何构造上述 Range
对象的例子?
Range 的构造函数似乎是私有的,因此静态方法可能是构造对象的首选方式.
例如,您可以使用静态方法 between
来构造 Range:
Range.between(100, 200);
不过还有其他的静态方法,就看你需要什么了.
How can I create a Apache Commons Lang 3.1 Range<Inreger>
object?
The JavaDocs say:
"An immutable range of objects from a minimum to maximum point inclusive."
"The objects need to either be implementations of Comparable or you need to supply a Comparator."
But when I try:
Range<Integer> range = new Range<Integer>(100, 200);
I get an error in my IDE that says required arguments are Integer, Integer, comparator.
Even though Integer
implements the Comparable
interface and thus I shouldn't need a extra comparator.
Can someone give me an example of how to construct the above described Range<Integer>
object?
The constructor of Range appears to be private so a static method may be the preferred way of constructing the object.
For example, it looks like you could use the static method between
to construct a Range:
Range.between(100, 200);
However there are other static methods, it just depends what you need.
