如何从文本文件中提取文字

Question

我一直在学习并叠加一个问题。我尝试从文本文件中搜索特定的名称和员工编号。我试图研究网上，但我没有找到特别的结果。

我怎样才能解决这个问题：

.\txtFileReader.java:15: error: cannot find symbol while((line = filescan.readLine()) != null)^symbol: method readLine() location: variable filescan of type Scanner 1 error

这里是我的代码：

File oldFile = new File("C:\\Tesseract-OCR\\" + name + ".txt"); 
try (BufferedReader reader = new BufferedReader(new FileReader(oldFile))) 
{ 
    StringBuilder contents = new StringBuilder(); 
    String text; 
    while ((text = reader.readLine()) != null) 
    { 
     String lineSeparator = System.getProperty("line.separator"); 
     contents.append(text).append(lineSeparator); 
     System.out.println(text); 
     if (text.contains("*Department: @INFO. TECH")) 
     { 
      int index = text.indexOf("TECH"); 
      text = text.substring(index, text.length()); 
      System.out.println("Result :" + text); 
     } 
    } 
} 

这里是我的Tesseract OCR转换的文本文件：

ATTENDANCE SHEET

*Department: @INFO. TECH *Date: @18/08/2017

*Year: @THIRD *Division: @C

*Subject Code: @TBGOZ

*Teacher Code: @ITIOOZO

@IT001 @ITOOZ @IT003 @ITOO4

m5 @IT006 @IT007 @IT008

@IT009 @5910 m wm-

m3 @IT014 m @IT016

@IT017 @IT018 m @9219

@IT021 mz @593 @IT024

m @IT026 @IT027 @IT028

@IT029 @m @IT031 W

@IT033 m4 @lT035 @IT036

我想在控制台上打印输出：

Department: INFO. TECH 
Year: THIRD 
Division: C 
Subject Code: @TBGOZ 
Teacher Code:ITIOOZO 

请告诉我上述问题的解决方案。

public static void main(String[] args) { 
     File oldFile = new File("C:\\temp\\test2.txt"); 
     try (BufferedReader reader = new BufferedReader(new FileReader(oldFile))) { 
      StringBuilder contents = new StringBuilder(); 
      String text; 
      String lineSeparator = System.getProperty("line.separator"); 
      while ((text = reader.readLine()) != null) 
      { 
       contents.append(text).append(lineSeparator); 
       // System.out.println(text); 
       String[] parsed = text.split("\\*"); 
       for (String p : parsed) { 
        if (!p.contains("Subject Code")) 
         p = p.replace("@", ""); 
        if (p.startsWith("Department")) { 
         System.out.println(p); 
        } else if (p.startsWith("Year")) { 
         System.out.println(p); 
        } else if (p.startsWith("Division")) { 
         System.out.println(p); 
        } else if (p.startsWith("Subject Code")) { 
         System.out.println(p); 
        } else if (p.startsWith("Teacher Code")) { 
         System.out.println(p); 
        }      


       } 
      } 
     } catch (Exception e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
     }
