The wrap() method of java.nio.DoubleBuffer Class is used to wraps a double array into a buffer. The new buffer will be backed by the given double array; that is, modifications to the buffer will cause the array to be modified and vice versa. The new buffer’s capacity and limit will be array.length, its position will be zero, and its mark will be undefined. Its backing array will be the given array, and its array offset will be zero....

The Java.DoubleAccumulator.accumulate() method is an inbuilt method in Java that updates with the given value in this DoubleAccumulator instance. It means that it takes a double value as a parameter and adds it up to this instance of DoubleAccumulator on which it is called....

The getAverage() method of DoubleSummaryStatistics class in Java is used to get the average of records in this DoubleSummaryStatistics....

DoubleStream mapToObj() returns an object-valued Stream consisting of the results of applying the given function....

The hashCode() method of Double class is a built-in method use to return the hashcode value of this Double object....

The limit() method of java.nio.DoubleBuffer Class is used to modify this DoubleBuffer’s limit. This method takes the limit to be set as the parameter and sets that as the new limit of this Buffer. If the mark of this Buffer is already defined and is larger than the new specified limit, then this new limit is not set and discarded....

The java.DoubleAdder.floatValue() is an inbuilt method in java that returns the sum() as an float after a narrowing primitive conversion. When the object of the class is created its initial value is zero....

Given a Double value in Java, the task is to convert this double value to string type....

The compareTo() method of java.nio.DoubleBuffer class is used to compare one buffer to another. Two double buffers are compared by comparing their sequences of remaining elements lexicographically, without regard to the starting position of each sequence within its corresponding buffer. Pairs of float elements are compared as if by invoking Double.compare(double, double), except that -0.0 and 0.0 are considered to be equal. Double.NaN is considered by this method to be equal to itself and greater than all other double values (including Double.POSITIVE_INFINITY). A double buffer is not comparable to any other type of object....

The accept() method of DoubleSummaryStatistics class in Java is used to accept the given value into this summary information....

The getMax() method of DoubleSummaryStatistics class in Java is used to get the maximum of records in this DoubleSummaryStatistics....

The duplicate() method of java.nio.DoubleBuffer Class is used to Create a new float buffer that shares the given buffer’s content....
