Method Detail
-
min
public int min()
Return the minimum value of the integer range.- Returns:
- the minimum value of the integer range
-
max
public int max()
Return the maximum value of the integer range.- Returns:
- the maximum value of the integer range
-
size
public int size()
Return the size of theIntRange
:max - min
.- Returns:
- the size of the int range
- Since:
- 3.9
-
stream
public IntStream stream()
Returns a sequential orderedIntStream
frommin()
(inclusive) tomax()
(exclusive) by an incremental step of1
.An equivalent sequence of increasing values can be produced sequentially using a
for
loop as follows:for (int i = range.min(); i < range.max(); ++i) { ... }
- Returns:
- a sequential
IntStream
for the range ofint
elements - Since:
- 3.4
-
of
public static IntRange of(int min, int max)
Create a newIntRange
object with the givenmin
andmax
values.- Parameters:
min
- the lower bound of the integer rangemax
- the upper bound of the integer range- Returns:
- a new
IntRange
object - Throws:
IllegalArgumentException
- ifmin > max
-
of
public static IntRange of(int value)
Return a new (half open) range, which contains only the given value:[value, value + 1)
.- Parameters:
value
- the value of the created (half open) integer range- Returns:
- a new (half open) range, which contains only the given value
- Since:
- 4.0
