There ya go, enjoy it

if you just want to make it work, you could replace those two lines

There are a few problems with your source code.
1. you used testScore.avg, but you did not declare avg in the variable testScore.
2.it is better to use type="number" as the input for the scores, or you need to add pattern="yourpattern" to disallow input of alphabets and special characters.
3.innerHtml is not the correct syntax, use innerHTML instead.
4.You only need to use one insertRow().As for the other fields, you should use insertCell()instead.
5.You need to insert a number into the insertRow/insertCell method. Eg.insertRow(x);
As for calculating the average, you can easily find it by adding the three fields and dividing them by the number of fields.
It is also better to hide the whole division instead of just the table, don't you think it's weird that you have button in the website but it does nothing?
You can also add the input fields inside a form, so that you can add mandatory attribute to the fields to ensure no null values will be added into the table.
You also need to add i++; in your function, otherwise all the numbers in the column "No" of your table will be the same number.
To hide/show a certain column in the table, you can use nth-child in the css/js.
Last and the most important issue, check your spelling. Some you use physics, some use physical, some use chemistry, but some use chemical, this is very confusing and will bring a hard time during maintenance or debugging in the future. You can also easily encounter a lot of errors this way. Eg. you declared as testScore.physical, but in the function you used testScore.physics
Choose one variable name and stick with it.

You are getting error because you are trying to update the collection of stdClass objects, which you got from the database.

Try like this:

it grabs the second item in the sorted scorelist and assigns it to 'b'.

If socrelist is [97,55,78,88] then b will equal 78

This is because 55 will be the "first" item with a place of 0

Since lists run [0, 1, 2, 3, ...]

Put @Transactional on marksheet service class.

@Transactional Public class MarksheetService {

}

Assuming userid,subject,type is unique

Set is a data structure that ensures that only one copy of each item inside it exists. So only copy of a person's name and its corresponding marks can exist.

You are not saving any data to dis field in your database, instead dis input field is saving data to gender field in your database. Do it like this
