java字符串练习

参考代码:

import java.util.Scanner;
public class Main
{
    public static void main(String []args)
    {
        Scanner scan=new Scanner(System.in);
        double yu=scan.nextDouble();
        scan.nextLine();
        String s1=scan.nextLine();
        String s2=scan.nextLine();
        double cnt=0;
        for(int i=0;i<s1.length();i++)
        {
            if(s1.charAt(i)==s2.charAt(i))
            {
                cnt++;
            }
        }
        if(cnt/s1.length()>=yu)
        {
            System.out.println("yes");
        }
        else
        {
            System.out.println("no");
        }
    }
}
