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)

public static Iterable<Integer> range(int min, int maxExclusive, int step)

range(min, maxExclusive)

public static Iterable<Integer> range(int min, int maxExclusive)

range with a step of 1

Doubles

range(min, maxExclusive, step)

public static Iterable<Double> range(double min, double maxExclusive, double step)

range(min, maxExclusive)

public static Iterable<Double> range(double min, double maxExclusive)

range with a step of 1.0

Client

class: RangeClient.java Presentation icon-72a7cf.svg
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:
