For loop - like Python range function

Question

I was wondering if in Java there is a function like the python range function.

range(4)

and it would return

[0,1,2,3]
         


        

Answer 1

Java 8 (2014) has added IntStream (similar to apache commons IntRange), so you don't need external lib now.

import java.util.stream.IntStream; 

IntStream.range(0, 3).forEachOrdered(n -> {
    System.out.println(n);
});

forEach can be used in place of forEachOrdered too if order is not important.

IntStream.range(0, 3).parallel() can be used for loops to run in parallel
