Please help a java noob

Here is the class i am working with.. the problem is that the last if statement never works. it seems as the x never registers the value of 5 i type in.

hey

try this:

 

public void chooseloacation() {

sc = new Scanner(System.in);

while (true) {

x = sc.nextInt();

if (x > 0 && x < 7) 

    break;

System.out.println("please select a number only from 1 to 6");

}

if (x == 5) {

System.out.println("poutses");

}

}

Firstly, it is helpful to comment out your code more for the end of each bracket. Secondly, try this.x instead of just x. Basically what the former does is say "The variable most in scope". This SHOULD fix the issue, but let me know if I overlooked anything.

to explain. 

if you declare a variable inside a loop, its scope will be limited to this loop. Also, if you declared it for the class. just use it inside any method, no need for redeclaring it.Otherwise it will be counted as 2 separate variables. 

define it before the loop then you can use it inside the loop and after it in the same method. I advise you to read about variable scope

why did you declare x twice and you should put public or private before the one in the beginning

@Tb428 He declared x once. Assigned it to a value once.

he declared it in the loop and in the beginning of the class

He assigned it from the output from Sc of type Scanner.
