Simulating nested loops

Question

In a beginner\'s programming book (free licence) there was the following code, dynamically creating nested loops in Java:

import java.util.Scanner;

public c         


        

Answer 1

It might be solved with this library, for example.

In your case you can implement loops so:

new Loops()
    .from(1).to(4)
    .from(1).to(4)
    .action(System.out::println);

The result:

[1, 1]
[1, 2]
[1, 3]
[2, 1]
[2, 2]
[2, 3]
[3, 1]
[3, 2]
[3, 3]
