X无法解析为变量|字符串/目录错误

标签: java string file directory

所以我正在从事课程工作,而且我对java很新。

我正在使用一个数据库,该数据库在与文件相关的目录中包含SQL文件。用户需要能够告诉程序查看这些SQL文件,它不能全部查看它们,因为它们有5000-8000个。

    String SystemDirectory = "F:/EVE M&R/bin/Resources/Systems";
    File[] Directories = new File(SystemDirectory).listFiles(File::isDirectory); 

我在第二行收到错误

    Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
    Syntax error on tokens, delete these tokens
     M cannot be resolved to a variable
     R cannot be resolved to a variable
     Syntax error on tokens, delete these tokens

答案 0 :(得分:0)

逃避&:

import org.apache.commons.lang.StringEscapeUtils;

public class testEscapeHTML{    
    public static void main(String args[]){
        String testStr = "< > \" &";
        System.out.println("Original : " + testStr);
        System.out.println("Escaped : " +   StringEscapeUtils.escapeHtml(testStr));

    }
}
