Method Summary

Modifier and Type	Method	Description
boolean	hasNext()	Test whether there are any more integers in the sequence; and change the state of the iterator so a call on IntIterator.next() delivers the next integer.

Constructor Details

IntStepIterator

public IntStepIterator(int start,
 int step,
 int limit)

Create an iterator over a sequence with regular steps

Parameters:

start - the first value to be returned

step - the difference between successive values (must be non-zero)

limit - if step>0, the iteration will not deliver any values greater than this limit; if step<0 the iteration will not deliver any values lower than this limit

Method Details

hasNext

public boolean hasNext()

Description copied from interface: IntIterator

Test whether there are any more integers in the sequence; and change the state of the iterator so a call on IntIterator.next() delivers the next integer.

The effect of calling #hasNext() a second time without an intervening call on #next() is undefined.

Specified by:

hasNext in interface IntIterator

Returns:

true if there are more integers to come

next

public int next()

Description copied from interface: IntIterator

Return the next integer in the sequence. The result is undefined unless #hasNext() has been called and has returned true.

Specified by:

next in interface IntIterator

Returns:

the next integer in the sequence
