What is only a semi colon not a error in Java or an IDE like netbeans?

In Java and IDEs like NetBeans, a single semicolon is not considered an error when it is used to terminate a statement. In fact, the semicolon is used to separate statements in Java code and is mandatory at the end of each statement for proper syntax. Without a semicolon, the compiler will throw an error indicating that the statement is incomplete.

However, if a semicolon is used in a context where it should not be present, such as after a conditional statement or inside a method declaration, it will be flagged as an error by the compiler or IDE. This is because the semicolon serves as a terminator for statements and should only be used in appropriate places within the code.

Overall, a single semicolon on its own is not considered an error in Java or IDEs like NetBeans when used correctly to terminate statements. It is an essential part of Java syntax and plays a crucial role in separating different parts of the code for proper execution.

I didnt realize there was only a semicolon in a line in my java as it was not considered an error by netbeans, I found it strange as only a semicolon by itsefl is not a statement right?

hmm; but why?

autumn venture
#

no idea, but it exists

#

there are some use tho

#

like while(true);

#

or if you prefer

# 
while(true)
  ;

#

That’s why if(;;) is an infinite loop

#

Initialize nothing

#

Keep doing contents till nothing happens

#

Do nothing

still smelt
#

None

#

It doesn’t do anything

#

It’s the equivalent of an empty line

#

And you can’t throw an error from a line that doesn’t do anything

its called a NOP

#

(no operation)

#

syntax-wise, it can have benefits to support that

#

as part of the buildings blocks of the language

#

so that u have a way to write a statement when the language expects one from u even if u dont want to write any

#

as shown above with the for(;;)

#

or a dummy lambda x -> ; etc

#

in practice however, chances are u will never use it

I've used while (somethingThatConsumesPartOf(x)); before. Because an empty body is rare, it was accompanied by a comment of course.

Also think about this

# 
doThing();;
#

very easy to do by accident, hard to find, doesn't actually affect anything to allow

#

so interpreting ; as "empty statement" has some value

got it thanks
