QUESTION
I ran into an issue I can't seem to solve, and all the searches I do are not completely relevant to the issue I am having, and trying to implement those things to solve my issue still doesn't work. I've spent an hour trying to find another question or post somewhere that would help but can't seem to find any specific to my issue (unless Google just doesn't want to work today).
I am trying to create a method that returns an array of all of the odd numbers between 1 and n, say in this example 1 to 255. I tried the following (here is the method currently):
...ANSWER
Answered 2021-Dec-03 at 04:41You don't need to add condition to check for each integer.
Here is a simple trick to create odds number:
Start with 1 and increase 2 for next element. ( 1,3,5...)
QUESTION
IM getting '0' value in the output whenever I call getAge method or calculateTotal amount from the main method. I created another method BusTicket in the main class to get details..by calling calculateTotal method from the BusTicket class in the main method reaps a zero value in the method..now calling the some method in the BusTicket method works fine and gives the required output..
//this is the main class
Main class ...ANSWER
Answered 2020-May-07 at 12:02The 'person' instance in your main method is a different object than the one on which you call setAge
. In getTicketDetails
you construct a new person and set the age on that instance but you're printing the age of the person constructed in main
.
QUESTION
this is my code..but I'm encountering an error of null pointer exception whenever I try to access private variables of "Category" class to "Product" class in the applyCoupon() method...
//main class
...ANSWER
Answered 2020-Apr-19 at 07:36This is because you don't initialize the internal category in your Product
constructor. Java's default initialization for Objects is null, which is why you get a NullPointer Exception when trying to call a method from this instance.
