Java runner class won't accept variables

Question

Okay so I have this Java object class that has methods to create a backpack object with options. I got all the methods working but the final method which displays the info isn't working correctly. It seems to not be accepting the parameters that are being inputted. I've included both the object class and the runner class.

/* Variables and parameters
 * Intro "Welcome to BackPackMaker, the ultimate backpack making experience. NOW LET'S MAKE SOME BACKPACKS!!"
 * Color(red,indigo,yellow,green,purple,orange,black,white)
 * No. of straps(1,2)
 * Size (small,medium,large,gigantic)
 * Pouches(1,2,3,4,5)
 * Water Bottle Slot(True,False)
 * Do you like Spongebob(True,False) if yes, "Hello SpongeBob, my name is PatBack!"
 * 
 * Use or statements in the if loop to keep things simple
 * The if loop consists of checking to see whether one of the variables was used.
 * 
 * All methods must be commented

Answer 1

You need to assign inputed value to the variable of your backpack object. After passing input in method -> this.pouches = pouches;

if(tpouch == 1 || tpouch == 2 || tpouch == 3 || tpouch == 4 || tpouch == 5){
            System.out.println(tpouch);
            this.pouches = tpouch;
            return tpouch;
        }

You receive the same values every time because you have created object of Backpack class and never changed its original values.

Also you need to display proper values, I don't really know why do you even care about "pouches" variable if there is no use for it. Try to keep it as simple as possible - if there is something you don't use - get rid of this.

Answer 2

You are just taking the input and not setting it to instance variable. For example while taking bag size String tsize = size; this sets the size to local variable tsize not the instance variable. It should be just this.tsize=size . And also in other methods.
