錯誤：在Java中

Question

找不到符號

我試圖找到一個解決方案，以我的時候在Eclipse運行，但它的工作原理編譯錯誤沒有，如果我嘗試編譯它在終端..

這裏有兩個班我已經開始寫

load.java

package doom; 

import java.io.BufferedReader; 
import java.io.FileReader; 
import java.io.IOException; 
import java.util.Arrays; 

public class load { 

    public int row; 
    public int columns; 
    private char[][] world; 

    public load() throws IOException{ 
     BufferedReader file01 = new BufferedReader(new FileReader("map1.txt")); 
     int rows = 0; 
     while((file01.readLine()) != null){ 
      rows++; 
     } 
     world = new char[rows][]; 
    } 

    public void getMap() throws IOException{ 
     BufferedReader file01 = new BufferedReader(new FileReader("map1.txt")); 
     String line; 
     int i = 0; 
     while((line=file01.readLine()) != null){ 
      world[i++] = line.toCharArray(); 
     } 
     System.out.println(Arrays.deepToString(world)); 
     System.out.println(world[4][6]); 
     file01.close(); 
    } 


} 

start.java

package doom; 

import java.io.IOException; 

public class start { 

    public static void main(String[] args) throws IOException { 
     // TODO Auto-generated method stub 
     load world = new load(); 
     world.getMap(); 
    } 

} 

這裏的電子我嘗試在終端中編譯時遇到了錯誤。

138-38-157-112:tet ciaranashton$ javac start.java 
start.java:9: error: cannot find symbol 
     load world = new load(); 
     ^
    symbol: class load 
    location: class start 
start.java:9: error: cannot find symbol 
     load world = new load(); 
         ^
    symbol: class load 
    location: class start 
2 errors 

Answer 1

你需要有load.class文件，因爲start.java指的是load.java。首先編譯load.java，你的程序就可以運行了。
