Simply because Math.max() attempts to convert its arguments to numbers. An array does not convert into a number, so you get NaN.
Calling Math.max(...lengths) splits the lengths array into several arguments, which works (so long as they're all numbers, of course).

r/Bitburner on Reddit: How to use math.max with array
October 21, 2021 -
I'm trying to get the maximum value in an array. What's the correct syntax to do this?
Alternative, is there a way to compare different variables and get the name of the variable with the highest value? Like
var memory = 10 var cores = 20 var level = 200 var node = 5 -> return "level"

You could use destructuring spread syntax: Math.max(...arr) That would pass all entries of the array as individual arguments to the function. Alternatively you could use "reduce", which would be a useful function to have in your toolbelt in general anyway. I don't remember the exact syntax rn, but I believe it looks something like: arr.reduce((a,b) => Math.max(a,b)) Someone will want to verify and/or correct me on this, and probably expand on it a bit.

These function expect just two arguments. If you want the minimum of an array you can use IntStream.
int[] a = { 1, 5, 6 };
int max = IntStream.of(a).max().orElse(Integer.MIN_VALUE);
int min = IntStream.of(a).min().orElse(Integer.MAX_VALUE);

You can simply used in-build java Collection and Arrays to sort out this problem. You just need to import them and use it.
Please check below code.
import java.util.Arrays;
import java.util.Collections;
public class getMinNMax {
public static void main(String[] args) {
Integer[] num = { 2, 11, 55, 99 };
int min = Collections.min(Arrays.asList(num));
int max = Collections.max(Arrays.asList(num));
System.out.println("Minimum number of array is : " + min);
System.out.println("Maximum number of array is : " + max);
}
}

October 17, 2019 - In the above function given the array1 we ask what is the max of that array. So that can check each item in the array, then we use the spread operator (…) to call the individual elements of the array. Simple! Another use is; let’s say you have a bunch of inputs you are collecting from different sources, but you only want the largest one to show, you can place the inputs in the parenthesis and let Math.max() do all the work for you.
