<@&987246399047479336> please have a look, thanks.

It's easier if you share code here using:

[elfin nimbus]

Please use this format for posting code:

```java
// Example java program
int value = 5;
System.out.println(value);
```

Which results in:

// Example java program
int value = 5;
System.out.println(value);

For syntax highlighting, you have to add the name of the language after the three backticks, like ```java. Please make sure to use exactly this format, so no space between the backticks and the language name, and a newline before the code starts. If done right, the syntax highlighting will even be applied to your text as you type, before sending.

But for non primitives you need to use .equals, not ==.

i had it working befor but now it refuses to run the if statement i took a screen shot of when it worked and compared it to now and it is the exact same

'''java private static final String TheOne21 = null;
private static Scanner sc;

public static void main(final String[] args) {
    sc = new Scanner(System.in);
    System.out.println("please enter your password: ");
    String passWord =sc.nextLine();
    
    if (passWord .equals(TheOne21)) {
        System.out.println("You may enter");
    } else {
        System.out.println("Please try again");
    }

would you be able to plug it in and see if it works?

[bronze verge]

It's 3 ` not "

You have a space after passWord.

Variables should be camelcased, and the thing you compare it to is null (TheOne21) so it will always be false.

Or if it's a constant, uppercased.

[wide orchid]

whats not camelcased? and what do i compair it to?

[elfin nimbus]

I uploaded your attachments as Gist.

[bronze verge]

TheOne21 if it's on class level should be: THEONE21, and I'd recommend something more descriptive like EXPECTED_PASSWORD.

And passWord.equals(TheOne21) currently translates to passWord.equals(null) which will never be true.

You haven't assigned a value the TheOne21.

[wide orchid]

so for TheOne21 should i set it to constant, local variable, field or perameter

and sorry im only 2 weeks in i just dont understand why this worked perfectly earlier and now it doesnt

any idea why it worked befor?

im not getting errors

[bronze verge]

In this case I'd expect a constant, but do assign it a value.

And I'd guess previously you assigned it a value.

And you won't get an error, it will just never be true.

Currently you just basically have if(1 == 2)

[wide orchid]

i cant figure out how to make it true

i cant asign it ThisOnw21

ThisOne21

[bronze verge]

You just need to assign whatever password you expect to ThisOne21 and enter it.

private static final String TheOne21 = "MY EXPECTED PASSWORD"

[wide orchid]

ohhhhhhh

but whatever i put there is wants me to make a constant or field'

[bronze verge]

Yes, and in this it's a constant.

if (passWord .equals(TheOne21)) { <= passWord is the name of the variable you assign the user's input to, the right hand side is the constant value.

[wide orchid]

i make it constant and then the new password = null

[bronze verge]

It's equivalent to:
if (passWord.equals("MY EXPECTED PASSWORD")) {

Which would be the same as:
if (sc.nextLine().equals("MY EXPECTED PASSWORD")) {

[wide orchid]

its just sending me in a constant never ending loop

every single time i add something i have to add it all over again

and again

constantly

[low slate]

what do you have so far

[elfin nimbus]

I uploaded your attachments as Gist.

[bronze verge]

umh...

you are assigning the variable to itself.

private static final String TheOne21 = ThisOne21;

You're not assigning it a String value.

Do you mean:
private static final String TheOne21 = "ThisOne21";
?

[wide orchid]

im an idiot

im so sorry to waste your time god i feel dumb

[bronze verge]

No problem, we all have to learn.

[wide orchid]

how would i make this to where theres 5 attempts to enter the correct password?

[low slate]

you could do a for loop

[wide orchid]

when this worked befor i added

[elfin nimbus]

I uploaded your attachments as Gist.

[low slate]

you need brackets after the for

[wide orchid]

{} these brackets?

[low slate]

yes

so for (int i = 0; i < 5; i++) {}

the code that you want repeated goes inside of the brackets

[low slate]

also this will never run

you declared a variable with the number 5 and the loop only runs if the variable is below 0, which is never

[bronze verge]

boolean passwordFound = false;
for (int i = 0; i < 5 && !passwordFound; i++) {
  System.out.println("Please enter your password - attempt #" + i+1);
  String passWord = sc.nextLine();
  passwordFound = passWord.equals(TheOne21);
}

if (passwordFound) {
  //
} else {
  //
}

[wide orchid]

so thats stating that if the password is false it reduces the number of attempts by 1 i appriciate it i was trying to put the expression after else but that just printed please try again 5 times haha

i really appreciate you guys sorry to take up so much time

[bronze verge]

No, it's an early exit condition. It will stop once there have been five tries OR the correct password has been found.

[wide orchid]

perfect thank you

took me a bit to get it to start at 1 and not 11 tho but i worked it out

[bronze verge]

No problem, good luck!
