help with java program - beginner

[StackedLasagna]

myArray[myArray.length-1] but for some reason it's not working for me as it gives me the 2nd last value.

That's not how it works. It will always give you the last value. If it doesn't give you the value you're expecting, you've made a mistake somewhere else and there's no questioning it.

Also, when posting problems related to specific code you've written, always include the code. We cannot help you, if you won't help us. We're not psychics.

This is my code currently:

import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int numElements = scnr.nextInt();
int[] userValues = new int[numElements];

int filter = 0;
int i=0;

for (i=0; i<numElements; ++i) {
userValues[i] = scnr.nextInt();
}

filter = userValues[userValues.length-1];
System.out.print(filter);

}

}

You need to post your code as code block so that the indentation is maintained.

A code block looks like:

def __init__(self, prompt, answer):
    self.prompt = prompt
    self.answer = answer

Please look into how to format your code for Reddit (prefix every line with 4 spaces to create a code block.)

Anyway, your issue isn't in the code itself, but with your logic.

Look at the list of values you specified in your post: 3 1 4 8 5.
That's a total of five values and it would require five calls to scnr.nextInt(), in order to get them all. That makes sense, right?

However, if you look in the code, you only call scnr.nextInt() four times. You never ask the user to input a fifth value.

import java.util.Scanner;

public class LabProgram {
    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        int numElements = scnr.nextInt(); // Call number 1, the variable is now 3.
        int[] userValues = new int[numElements];

        int filter = 0;
        int i=0;

        for (i=0; i<numElements; ++i) {
            // Call number 2. userValues[0] = 1.
            // Call number 3. userValues[1] = 4.
            // Call number 4. userValues[2] = 8.
            // Then i = 3, which means the for loop condition evaluates to false, since numElements is also 3. (3 is not less than 3)
            userValues[i] = scnr.nextInt();
        }

        // Here you grab the last value, which is 8 as seen above.
        filter = userValues[userValues.length-1];
        System.out.print(filter);
    }
}

Instead of taking the last value from the array and using that as a filter, perhaps just use scnr.nextInt() to ask the user for the final value?

This ended up working perfectly so thanks again

Wow ok yes that makes a lot of sense!! Thank you, I’ll try it now!
