What is the wrong in this java code??? Please help?

MY SPOUSE AND I developed any java code to obtain the average regarding 10 volumes..Even though this is the simple program i made use of multiple tuition and ways to improve my knowledge.but next time i run this software i determined some slips.i here’s so fortunate to anyone who can help me with this..thanks
This is the signal..

significance java.util.Shield;
training apples
open public static void main(String args)
Shield input=new Scanner(System.in);
int i=0;
two times num, tot=0, avg;
while(i<10)
Process.out.println(“Enter your number”);
num=input.nextDouble();
tuna tunaObject=new tuna();
tot=tunaObject.add(num);
i++;

avg=tunaObject.average(tot);
tunaObject.output(avg);

training tuna

open public double add(double num)
two times sum;
sum+=num;
give back sum;

open public double average(double tot)
give back tot/10.0;

open public void output(double avg)
Process.out.println(“The average is “+avg);

Hello presently there!

Please be patient in order to read the following, I promises it will assist you to.

I will be very glad to view that you might have taken way up a challenging method to a simple problem.It will certainly indeed allow you to master the particular language with more speed, as each and every problem demands that you simply use different features.
To start with, you should give yourself a pat to the back regarding writing code inside correct syntax.That’s really good

Nevertheless, let me go back to the strategy to your queries.

1st, lets study the school ‘tuna’.
JUST ONE.The procedure ‘add(double num)’ should preferably return the sum of the the figures entered as while it is known as.But this will not offer you the genuine sum nevertheless only offers back the quantity because, the varied ‘sum’ is definitely being re-declared plus initialized for you to 0 each time you call this process.Thus the last sum is actually erased.To stop this in order to obtain the precise sum regarding numbers, you’ll have to declare ‘sum’ like a global variable in this class.In this way, the benefit of ‘sum’ is definitely retained until finally the object dies.Thus now, your ‘tuna’ category will seem like this:

training tuna
two times sum;

open public double add(double num)
sum+=num;
give back sum;

open public double average(double tot)
give back tot/10.0;

open public void output(double avg)
Process.out.println(“The average is “+avg);

TWO.In this class ‘apples’, examine this ‘while’ never-ending loop closely and you will see this statement — ‘tuna tunaObject=new tuna(); ‘.This is actually potentially the single most dangerous valid flaws.You should avoid instantiation connected with objects or perhaps declarations involving any sort in a loop, particularly when the memory allocation is done dynamically, as in this instance.What happens suggestions that when the loop is done, when the idea reaches this specific statement, an innovative object from the name ‘tunaObject’ is created following your previous one ‘tunaObject’ is usually deleted in the memory through JAVA ‘garbage collecters’.The reason is , names associated with objects are limited to us to identify them.There’re actually adresses
