How do I find the maximum and minimum value of an array with loops?

For some reason I don’t know Processing is not giving the minimum and maximum values when I used the standard logical code to get minimum and maximum values so I resorted to use Processing Syntax. Good luck with your project.

int houses = {25,30,18,105,33,10,17,8,65};  
void setup(){  
size(400,400);  
background(200);

int maxXM = max(houses);  
int minXM = min(houses);  
//println(maxXM);  
//print(minXM);

}

void draw(){  
}

Processing’s container IntList has both **min()** & **max()** methods:

> **[Reference](https://processing.org/reference/IntList_min_.html)**
>
> Return the smallest value.

> **[Reference](https://processing.org/reference/IntList_max_.html)**
>
> Return the largest value.

How about taking a peek on how they’re implemented straight from their source?

Hello @Chigoz,

Please follow instructions here for posting code:  
[https://discourse.processing.org/faq#format-your-code](https://discourse.processing.org/faq#format-your-code)

This is what you are posting:  
 ![image](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/4/5/45a6f3105f6d6c7d599f52551258371620986da3.png)

This is what you should be posting:

```auto
int [] houses = {25, 30, 18, 105, 33, 10, 17, 8, 65};

```

Properly formatted and posted code helps the community focus on the code instead of the errors from a quick cut and paste.

I do not use my phone for this.

I suggest you start a _ **separate topic on the subject** _ and users with experience can advise you.

This would be of great benefit to others as well!  
There are a lot of sloppy posts recently and this may be related to their development environment.

Details are important.

What are you using to develop your code on the phone?

Recently for some reason I don’t know some websites do not load on my Google Chrome browser hence after I write the code in Processing IDE I transfer it over the internet to my phone and if there is any need to do further work on the code. I edit the code with my phone and run it on OpenProcessing.

No need for a long winded approach, depending on the array type, if its just ints or floats its simple

```auto
int[] list = {1,6,7,3,5,6,3,4,2,8};

println(max(list));

```

The need is determined by the the original poster.

The original poster may be a beginner and understanding basic loops and search algorithms is an important first step and a very common question.

It is important to master the basics and also nice to have the options of the helper methods for consideration.

I may have been a bit long winded…

No, not long winded, you make a good point, its better to know HOW the functions work at their core then just using them

The thing is that the loop goes on and one, and I have the maximum and minimum value a lot of times.

Hello @mvb,

Think about what the loop is doing and where you want these statements:

```auto
  print(min);
  print(max);

```

Consider using _println()_ instead.

I am seeing “this piece of code” in other posts as well with different user names.

Is this a homework assignment?
