使用方法“输入无法解决”

Question

package methods;

import java.util.Scanner;

public class DisplayBox {

public static double FindDimensions (int length, int width) {
    Scanner scanner = new Scanner (System.in); 
    int box ; 

    System.out.println ("Please enter the length of the box"); 
    length = input.nextInt();//input cannot be resolved 
    System.out.println (" Please enter the width of the box");
    width = input.nextInt(); //input cannot be resolved 


    return box  ; 
}


public static void main(String[] args) {
    // TODO Auto-generated method stub


    }
}

我不明白为什么它一直说输入无法解决。我知道这是一个非常基本的问题，但我需要你的帮助。
