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

As far as I know, there's not an equivalent function in java. But you can write it yourself:

public static int[] range(int n) {
    int[] ans = new int[n];
    int i;
    for(i = 0; i < n; i++) {
        ans[i] = i;
    }
    return ans;
}
