BufferedReader error in Fibonacci sequence in Java

Question

I am new to Java, coming from a C background. While trying to implement a Fibonacci Sequence,I received the following error:

 error: cannot find symbol
    n = Integer.parseInt(br.readline());
                           ^
 symbol:   method readline()
 location: variable br of type BufferedReader

The program is as follows :

import java.io.*;

public class fibonacci
{
public static void main(String args[])throws IOException
{
    int n;
    InputStreamReader read = new InputStreamReader(System.in);
    BufferedReader br = new BufferedReader(read);

    System.out.println("enter the value of n");
    n = Integer.parseInt(br.readline());

int fib[];
    fib[1]=1;
    fib[2]=1;
    for(int i=3; i<=n; i++)
    {
        fib[i] = fib[i-1] + fib[i-2] ;
    }

    System.out.println("the"+n+"th fibonacci term is "+fib[n]);
}
}

Kindly help.

Answer 1

Java is case sensitive

n = Integer.parseInt(br.readline());
                            ^

should be

n = Integer.parseInt(br.readLine());

Answer 2

Because it should be readLine instead of readline. Please keep in mind that JAVA is case-sensistive. And please use the IDE, it will catch such mistakes even before compilation.
