Hi, im doing some problems but i dont really now how recognize the EOF in Java.

If i use this to read from standar input:

Code: Select all

                BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String line = "";
		
		while ((line = br.readLine())!= null ){
			/*
                        */
		}
	}

Can anyone help me .. Thanks.

BufferedReader.readLine returns null on EOF, so what's exactly the problem with your program?

your doing it correct... however your syntax is messed up (i think) instead of "while ((line = br.readLine())!= null )" it should be

Code: Select all

String line = br.readLine();
while(line != null)
{
  //Your code
  line = br.readLine();
}

I could be wrong but I never assigned a value and checked a condition at the same time..
