What is the correct way to use operator brackets?

Question

Java

Good afternoon!
I always used operator brackets when working with loops, an if block, regardless of whether several statements were nested inside or not. The programming teacher says that the operator bracket should only be used when there are several operators inside, otherwise it should be written in this form:

if() k=321;
else z = 256;

I've always done this before:

if(){
k=321;
}else{
z = 256;
}

It seems to me that in the latter version, the readability of the code becomes much better.
Can you please tell me which style to follow?

Answer 1

The programming teacher says that the operator bracket should only be used when there are several operators inside, otherwise it should be written in this form

tell him he's a theoretician.
When you need to add the second condition, the brackets will definitely be needed. This time.
Second, readability is better.
Thirdly, the possibility of errors is excluded.
The presence of brackets does not affect anything, there are no minuses. Only pluses.

Answer 2

It's best to use vendor-recommended coding rules

Answer 3

The Yii2 documentation recommends

if() k = 321;
else z = 256;

but not

if() 
  k = 321;
else 
  z = 256;

I write myself

if(){

  k = 321;
} else {

  z = 256;
}

It may be overkill, but it's easier for me. An empty line is more striking, you can see where it started, where it ended.

Answer 4

in descending order of priority:
in my humble opinion, if curly braces can be supplied, they should be.
// and don't forget about code formatting!!1

Answer 5

We are required to use this code at work:
if(){
k=321;
}else{
z = 256;
}

Answer 6

Thank you all very much for your replies.
Then I will not exclude the use of brackets when working with blocks that have only one operator inside. If the teacher swears, then I will give him a link to the repository.

Answer 7

You are right in an unexpected place.
Your version is potentially less problematic when debugging (when you constantly comment on pieces of code and uncomment them back).
The instructor's option is "kinda easy to read" but may cause unexpected syntax shifts.
I hope you have indents.
