编译错误 - 无法在java错误中找到或加载类

Question

package IO;
import java.io.*;
import java.util.ArrayList;

public class driver {

    public static void main(String args[]) {

        int s;

        try {

            //Scanner in = new Scanner(System.in);
            //System.out.println("Enter The number of files you want to create");
            //s = in.nextLine();
            //takes the number of files

            ArrayList<String> obj = new ArrayList<String>();
            BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
            System.out.println("Enter the number of files you want to create");
            String num = br.readLine();
            int x = Integer.parseInt(num);

            // takes the names of file
            for (int i = 0; i < x; i++) {
                System.out.println("Enter the name for file:");
                String name = br.readLine();
                Integer.parseInt(name);
                obj.add(name);
            }

        } catch (IOException o) {
            System.out.println("Exception^^^^^^^^^^^^^");

        }
    }
}

上面是我的代码，但是当我在命令行上编译它，如javac driver.java然后java驱动程序，它给我错误，无法加载主类主...请帮我排序这个错误..这代码btw包含稍后要实现的文件处理！

Answer 1

我修改了您的代码，请检查以下适用于我的代码..

import java.io.*;
import java.util.ArrayList;

public class Driver{

    public static void main(String args[]){

    int s;

    try{
        ArrayList<String> obj = new ArrayList<String>();
        BufferedReader br= new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter the number of files you want to create");     
        String num = br.readLine();
        int x=Integer.parseInt(num);

        // takes the names of file

        for(int i=0;i<x;i++){
        System.out.println("Enter the name for file:");
        String name = br.readLine();
        Integer.parseInt(name);
        obj.add(name);
        }
    }catch(Exception e){

    }
    }
}

1. 您是否正确找到文件？
2. 删除package IO;，然后进行编译。 它编译成功。
