Constructor Detail

Range

public Range(int start,
             int max,
             int step)

Creates a sequence \( a_i, i < 0 <= n \) where \( a_i = start + i * step \) and \( n \) is such that \( a_n <= max \) and \( a_{n+1} > max \).

Parameters:

start - First value of the range.

max - Last value of the range that satisfies the above construction rule.

step - Increment.

Method Detail

size

public int size()

Gets the number of elements contained in the range.

Returns:

the size of the range.
