Answer 1

Mamun Rahman as you continue to practice more Java, you will use Scanner class often and become familiar with.
Code provided does cover probably more then you need at the moment, so try to figure what you can rid of, break the code, play with it and don't forget to enjoy. :-)

Answer 2

● For comparing content of Strings U can make use .equals() method :
Example : String a="a", b="a";
System.out.println(a.equals(b)); //true
● make use of if() & else if() conditions & at last an else() condition for "Out Of Stock"

Answer 3

You should use Scanner to take input. Remember to import it from util library. Then, check the user input on all conditions using if and else statements.
That can be simple algorithm. Give it a try by yourself.

Answer 4

The Question is: did you tried to find an own Solution for this Problem? It is always better to write a Code by yourself. If it won't work you can post it here and the Community will help you to fix it. But you should not wait that anyone here does the Job for you.

Answer 5

i’ve been thinking just trying to figure out where to start. i just started learning and finding it really challenging ..

Answer 6

im going to try and see how far i can do , will keep u guys updated. thanks all of you :)

Answer 7

Yes, it can be done very easy.
As suggested use Scanner for input. Next, in my opinion, you should check for switch/case option for comparing and if you need all of this to be executed more than once, then put it all in while loop.

So, you need only three main things to learn. Easy, right?

Look forward to see your progress.

Answer 8

im still struggling on how to start with scanner :(
how do i put the items under which aisle...

Answer 9

Ok,
compare this with your code and try to find what's troubling you. Or ask what is unclear.

Answer 10

i appreciate it
im trying to understand the whole coding you did. i guess i still need to learn a lot about scanner

Answer 11

no intellij

Answer 12

yes i am really excited since i started and putting a lot of time
i guess im just a slow learner
im taking a online course trying to learn as much as i can. i am going to play with your codes and see what i can fogure out :)
you are a great help. in this app you can’t chat one to one right?

Answer 13

Scanner in = new Scanner(System.in);
System.out.println("Welcome to our supermarket");
in.nextLine();
String Item = "Milk";

switch ("itemLocated") {
    case "Milk":
    case "Eggs":
    case "Donuts":
        System.out.println("Aisle8");
        break;
    case "French fries":
    case "Frozen pizza":
        System.out.println("Aisle7");
        break;
    case "Candy":
        System.out.println("Aisle3");
        break;
    case "Diapers":
        System.out.println("Aisle1");
        break;
    case "Apple":
    case "Orange":
        System.out.println("Aisle2");
        break;
    default:
        System.out.println("Out of stock");
}

        System.out.println("Milk is located ");

(what should i change in this to get it right)

Answer 14

String item = in.nextLine(); //to save user input
switch(item) // to examine condition
I can see a great progress... Do you?

Answer 15

when i print it out
it comes ‘out of stock’ first and it prints ‘looking for milk’

Answer 16

Scanner in = new Scanner(System.in);
System.out.println("Welcome to our supermarket");
String item = in.nextLine();
in.close();
switch (item) {
case "Milk":
case "Eggs":
case "Donuts":
System.out.println("Aisle8");
break;
case "French fries":
case "Frozen pizza":
System.out.println("Aisle7");
break;
case "Candy":
System.out.println("Aisle3");
break;
case "Diapers":
System.out.println("Aisle1");
break;
case "Apple":
case "Orange":
System.out.println("Aisle2");
break;
default:
System.out.println("Out of stock");
break;
}

System.out.println(item + " is located ");

Using Eclipse?
Ok, txs. There is just minor corrections here compared to your code. Congrats!

Answer 17
