Do all over again, how?

(RESTART THE WHILE LOOP)
Ok so I got a loop

while(true){
if(bla == 1){
bla bla bla
}else{
return to the start point <<while(true)>>
}
bla bla
bla bla bla
bla
}

How do I do something like that?

[doWhile]

See Branching Statements (The Java™ Tutorials > Learning the Java Language > Language Basics), especially the last example on that page

But what if I've got "if" inside of "if" inside of "if" and there is "else" on the last if, and I need to restart the loop in that else statement?
The examples for that ^^^ didn't work...

The next to the last example at that link may be what you are looking for.

I tried the
bla:
break bla;
It gives me an error "The label bla is missing"

That doesn't help us diagnose the problem. Provide an SSCCE that shows what you did.

Ehh ok:

Simply, it checks if user exists in the file and if the password is right. if not then it restart almost everything

[doWhile]

For future reference, that is not an SSCCE. Don't expect unpaid volunteers to wade through your code. In this case you are in luck it is just a syntax error: the label has to identify the loop

MYLABEL: while(true) {
        if ( somecondition ){
            break MYLABEL;
        }
    }

Note the location of the label - before the loop, not before the variables that are before the loop.

Ohhh, thanks! And ok I will do the SSCCE next time..
