Help: java break

[chathura86]

Hi.

I have a little problem with java.

Please check the following java script:

class Break{
   public static void main(String args[]){
   boolean t =  true;
		
   a: {
         b: 
            c: {
               System.out.println("Line 4");
               if(t) break b;
               System.out.println("Line 7");
            }
            System.out.println("Line 9");
			
         System.out.println("Line 11");
      }
   }
}

and i found that the output is

Line 4
Line 9
Line 11

Please some one explain me how does this come

Thanks & Regards,

Welcome to TSDN.

if u r from C background then it ll be easy to understand this code.
assumming this .. now look
in java break label; or continue label; these serve as goto as in C.

in java a label immediately follwed by a label or starts with a scope ... and the label ends where the scope ends.

now look at this code ...

A:
B:
{
//Some lines ------------1 ==========it ll print.
break A or B; //Here control ll jump to Some Lines 3
//Some lines ---------------2 ============ it ll not.
}
//Some lines --------------3 ============ it ll print.

now ..............

A:
//Some lines =========Here ll an error (undefined label A)
B:
{
//Some lines ------------1 ==========it ll print.
break A; //Here control ll jump to Some Lines 3
//Some lines ---------------2 ============ it ll not.
}
//Some lines --------------3 ============ it ll print.

now............ .

A:
//Some lines =========No error because B label defined well.
B:
{
//Some lines ------------1 ==========it ll print.
break B; //Here control ll jump to Some Lines 3
//Some lines ---------------2 ============ it ll not.
}
//Some lines --------------3 ============ it ll print.

so the label should be defined well with a scope or immediately follwed by another label, then two labels r well defined.

now i think u understand my point of view.
so u can figure out the output now.

best of luck.
kind regards.
