Curly brackets?

Question

Hi there! I'm super new to all this Java stuff and I'm struggling to comprehend the concept of 'curly brackets' or these things '}'. From what my developer friend has told me, they sort of class methods together, but I dont understand when to use them. Sometimes methods end with ; or }, so if anybody could clarify when to use them and how they work, that would be most appreciated!

Thank you very much !

Answer 1

Brackets are to collect subgroups of your program. Statements to be executed repeatedly (loops), conditionally (if, else), or under a particular identifier (methods, classes, enums) are all meant to be within curly braces.

Java statements end with a ;, so when you call a method, you'll have the semi-colon there. It's also used when you're declaring a method, but not implementing it right away (since that is a statement).

Does that help?

Answer 2

{} shows you the block or scope of a subgroup. Everything inside the block is what the group contains. So a class will contain everything inside the block.

Class myClass
{// begin class

//inside class

}/end class

void myMethod()
{//begin method

// inside method

}//end method

You can also have nested blocks, here's an exanple with if statements:

if(condition)
{// begin 1st if

//inside 1st if, before 2nd

if(condition
{//begin 2nd if, inside 1st if

//inside 2nd if

}//end 2nd if

//inside 1st if, but after 2nd

}//end 1st if

Statements end with ;
The ; is used to tell the compiler where the end of the statement/command is.
