Code To Implement
class: | Iterables.java | |
methods: | range range range range |
|
package: | range.warmup | |
source folder: | src/main/java |
Each of the overloaded range methods must return an Iterable of the appropriate generic type. We have provided nested inner classes for IntegerRangeIterator and IntegerRangeIterable. Feel free to implement these or delete them if you would prefer to build your Integer range methods with anonymous inner classes and or a lambda and an anonymous inner class. For the Double range methods, you can define your own named nested inner classes or got the anonymous inner class/lambda route as you wish.
Integers
range(min, maxExclusive, step)
range(min, maxExclusive)
range with a step of 1
Doubles
range(min, maxExclusive, step)
range(min, maxExclusive)
range with a step of 1.0
Client
class: | RangeClient.java | |
package: | range.client | |
source folder: | src/main/java |
The code:
for (int i : Iterables.range(4, 12)) { System.out.println(i); } System.out.println(); for (double d : Iterables.range(3.0, 7.1, 0.25)) { System.out.println(d); }
produces the output:
4 5 6 7 8 9 10 11 3.0 3.25 3.5 3.75 4.0 4.25 4.5 4.75 5.0 5.25 5.5 5.75 6.0 6.25 6.5 6.75 7.0
