when to use ;

Question

hi i am pretty confuse when to use ; and when to not can anyone clear my doubt .

Answer 1

It goes at the end of every statement, however is not required at the end of blocks.

Ex/
if(condition){

}
// no semi-colon needed here.

The {} is the scope or block of the if statement.

Another example/

void myMethod(){

int a = 3;
// semi-colon needed

} // no semi-colon needed

Answer 2

You put them after every statement. Basically everything is a statement that isn't a code block in Java. Code blocks are written with these curly braces { }

code blocks can be class definitions, function definitions, loop blocks, if, else and switch blocks
for example:
class A {

}

or
if(condition) {

}
are code blocks

other than those are statements, like variable definitions, operations with variables, function calls, etc.

i.e.
int a;
double b = 3.0;
a = 2;
a = b;

and so on

Answer 3

I don't know about Java, but I think you put that at the end of every line.

Answer 4

It still depends whether or not your talking about a block or statement.
Declaration of a String? Yea.
Creating a method with a String return type? No.
Returning a String? Yea.

Best to just know, not for blocks, yes for statements, so you don't need to keep asking yourself.

Answer 5

You should use it at the end of the statement. Like declaring variables. At the end of operations like arithmetic int x=5+3;
