BufferedReader

[Lindsey]

Ok. Here is my code. I need to know why i keep getting the same error message.
The error message is also posted.
import java.io.*;
public class more{
public static void main(String [] args){
BufferedReader a = new BufferedReader (new
InputStreamReader (System.a));
String oneline;
int countline;
int countcol;
countcol = 0;
try{

while ((oneline = a.readline() ) != null){
oneline = a.readLine();
System.out.println(oneline);
if (countcol >= 80){
System.out.println(" ");
countline =+ 1;
if (countline == 20){
break;
}
}
}
}
catch( Exception e )
{ System.out.println(e);}
}
}



Error...

more.java:6: No variable a defined in class java.lang.System.
InputStreamReader (System.a));
^
more.java:13: Method readline() not found in class java.io.BufferedReader.
while ((oneline = a.readline() ) != null){
^




please help!!!

1- it is java convention that every class name should starts with a
capital letter so call your class "More" instead of "more" (this is
not an error but it is a good practice to follow conventions)

2- the error message:
more.java:6: No variable a defined in class java.lang.System.
InputStreamReader (System.a));

means exactly what it says "a" is not a variable in class
java.lang.System, i guess you are trying to read from the consol so it
should be :

BufferedReader a = new BufferedReader (new
InputStreamReader (System.in));

3- the second error mesage:
the correct method name is "readLine()" with capital (L)

good luck,

Ako

And you didn't ask this yet, but there's a reason your program is only
processing every other line of the input. That's because you read a line
into the variable "oneline" in your while-clause, then in the very next line
of code, you read another line into that same variable. So you will only be
processing the even-numbered records and ignoring the odd-numbered records.
