Guys can you help me? Java encapsulation

Answer 1

You have to call your readInput() method in main
public static void main(String[]args){
LabExer2 lab = new LabExer2();
lab.readInput();
System.out.println(lab.itemName);
System.out.println(lab.itemQuantity + "" + lab.itemPrice);
}

Scanner s = new Scanner(System.in);
System.out.println("Enter name of item you are purchasing.");
itemName = s.nextLine();
System.out.println("Enter the quantity and price separated by a space.");
itemQuantity = s.nextInt();
itemPrice = s.nextDouble();
}
public void writeOutput(){
System.out.println(itemName);
System.out.println("You are purchasing " + itemQuantity + " at " + itemPrice + " each.");
}

return itemName;
}
public double getTotalCost(){

also print result of getTotalCost() at the end
setName() and setTotalCost() are wrong because
you assign class field to method input parameter
newItemName = itemName;
