args [] of main takes only ten elements?

Question

In a video of the Oracle University for Java certification, the instructor just said that "the size of args is ten, so we can only send a maximum of ten elements". Has anybody heard of this?

I just tried it and it doesn't seem right.

package tests;

public class MainArgsSize {

    public static void main(String[] args) {
        for (String st : args) {
            System.out.println(st);
        }
    }
}

java tests.MainArgsSize 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Answer 1

From the Java documentation:

A Java application can accept any number of arguments from the command line.

^[source]

However, these arguments are passed in the form of an array. From this link here: Do Java arrays have a maximum size?, the size of an array was discussed as being:

Integer.MAX_VALUE - 5

Therefore, that should be the limit.

Edit: Thanks for @MrLore who provided the following link discussing the limits on Unix machines in his comment above:
