Question

我是Java新手，来自C背景。在尝试实现Fibonacci序列时，我收到以下错误：

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

该计划如下：

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]);
}
}

请帮助。

Answer 1

Java区分大小写

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

应该是

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

Answer 2

因为它应该是readLine而不是readline。请记住，JAVA具有案例敏感性。请使用IDE，即使在编译之前它也会遇到这样的错误。
