Create an object for your function. Int e= min(a,b); Then search for the smallest value And when your stuck check out the Community help functie.

I just had an observation. Since the methods are public and using the same int a, b and for the other method c and d; Does it mean it is using the same variable if we use the 2 variable method inside the 4 variable method? Its obvious that yest this is true but I just wanted someone to confirm my "theory". I think this is a true observation as the methods are public and therefore able to share the 2 variables amongst each other.

It easy , -use the previous task(Minimum of three numbers ) -Call min(a,b) from the min(int a, int b, int c, int d) method to fix the overloading error that Intellj might display . -use if and if esle , else ..

I had completed all the requirements in my program except for "The min(a, b, c, d) method must use the min(a, b) method.". So I looked for help and found out to put in "int min1 = min(a,b);" in the "min(a,b,c,d)" function and it passed the requirements. I am not sure if it's the correct way of solving this task because I think they wanted me to actually use this line of code more.

for example, you need to use the perimeterOfSquare method, which should calculate the perimeter of a square. Correct version:

public class Solution {
    public static void main(String[] args) {
        int perimeter = perimeterOfSquare(2);
        System.out.println(perimeter);
    }

    public static int perimeterOfSquare(int side) {
        return 4 * side;
    }
}

Wrong version:

public class Solution {
    public static void main(String[] args) {
        int perimeter = perimeterOfSquare(2);
        System.out.println(4*2);
    }

    public static int perimeterOfSquare(int side) {
        return 4 * side;
    }
}

Output is the same, but ...

Quite frustrated I found this task really easy, I solved it in three different ways on eclipse without problems instead here the task can't be accepted.In all 3 compilation I always respected what was requested and still I can't pass the task. I start to think that the program pretend exactly the writing that was saved in it so at this point is all about fortune to get it. I'm concern about the future tasks when stuff start to be harder.

Hi, I got the right output (the min number for each method) but the test failed on the last statement: The min(a, b, c, d) method must return the minimum of the numbers a, b, c, and d >.> If anybody could explain why that would be wonderful and very useful to me :)
