Package Summary Overview Summary

### class:IntSummaryStatistics [NONE]
- All Implemented Interfaces: `IntConsumer`
                                                                                      public class IntSummaryStatistics
      extends Object
      implements IntConsumer
  A state object for collecting statistics such as count, min, max, sum, and average. This class is designed to work with (though does not require) streams. For example, you can compute summary statistics on a stream of ints with:
       IntSummaryStatistics stats = intStream.collect(IntSummaryStatistics::new,
                                                      IntSummaryStatistics::accept,
                                                      IntSummaryStatistics::combine);
  `IntSummaryStatistics` can be used as a reduction target for a stream. For example:
       IntSummaryStatistics stats = people.stream()
                                          .collect(Collectors.summarizingInt(Person::getDependents));
This computes, in a single pass, the count of people, as well as the minimum, maximum, sum, and average of their number of dependents. Implementation Note: This implementation is not thread safe. However, it is safe to use `Collectors.summarizingInt()` on a parallel stream, because the parallel implementation of `Stream.collect()` provides the necessary partitioning, isolation, and merging of results for safe and efficient parallel execution. This implementation does not check for overflow of the sum. Since: 1.8

### constructor:<init>() [NONE]
- #### IntSummaryStatistics
      public IntSummaryStatistics()
Constructs an empty instance with zero count, zero sum, `Integer.MAX_VALUE` min, `Integer.MIN_VALUE` max and zero average.

### constructor:<init>(long,int,int,long) [NONE]
- #### IntSummaryStatistics
                                                                                                      public IntSummaryStatistics​(long count,
                                  int min,
                                  int max,
                                  long sum)
                           throws IllegalArgumentException
Constructs a non-empty instance with the specified `count`, `min`, `max`, and `sum`. If `count` is zero then the remaining arguments are ignored and an empty instance is constructed. If the arguments are inconsistent then an `IllegalArgumentException` is thrown. The necessary consistent argument conditions are: `count >= 0` `min <= max` API Note: The enforcement of argument correctness means that the retrieved set of recorded values obtained from a `IntSummaryStatistics` source instance may not be a legal set of arguments for this constructor due to arithmetic overflow of the source's recorded count of values. The consistent argument conditions are not sufficient to prevent the creation of an internally inconsistent instance. An example of such a state would be an instance with: `count` = 2, `min` = 1, `max` = 2, and `sum` = 0. Parameters: `count` - the count of values `min` - the minimum value `max` - the maximum value `sum` - the sum of all values Throws: `IllegalArgumentException` - if the arguments are inconsistent Since: 10

### method:accept(int) [NONE]
- #### accept
      public void accept​(int value)
Records a new value into the summary information Specified by: `accept` in interface `IntConsumer` Parameters: `value` - the input value

### method:combine(java.util.IntSummaryStatistics) [NONE]
- #### combine
                                                                                                      public void combine​(IntSummaryStatistics other)
Combines the state of another `IntSummaryStatistics` into this one. Parameters: `other` - another `IntSummaryStatistics` Throws: `NullPointerException` - if `other` is null

### method:getCount() [NONE]

### method:getMin() [NONE]
- #### getMin
      public final int getMin()
Returns the minimum value recorded, or `Integer.MAX_VALUE` if no values have been recorded. Returns: the minimum value, or `Integer.MAX_VALUE` if none

### method:getMax() [NONE]
- #### getMax
      public final int getMax()
Returns the maximum value recorded, or `Integer.MIN_VALUE` if no values have been recorded. Returns: the maximum value, or `Integer.MIN_VALUE` if none

### method:getAverage() [NONE]
- #### getAverage
      public final double getAverage()
Returns the arithmetic mean of values recorded, or zero if no values have been recorded. Returns: the arithmetic mean of values, or zero if none

### method:toString() [NONE]
- #### toString
                                                                                                      public String toString()
Returns a non-empty string representation of this object suitable for debugging. The exact presentation format is unspecified and may vary between implementations and versions. Overrides: `toString` in class `Object` Returns: a string representation of the object.
