Java 逐行读取文本区域并分配变量

我需要在

TextArea

的每行文本中添加变量。

TextArea

已编码，工作正常。我可以使用

TextArea.getText（）从
TextArea
检索信息
为了将其分解，我尝试使用一个
BufferedReader
。不幸的是，这不起作用。有没有其他的方法？以下是如何在文本区域中写入信息的示例：

BufferedReader inStream= new BufferedReader 
(new InputStreamReader(TextArea.getText()));

String workerName = "";

String workerDepartment = "";

int workerNumber = 0;

String line = inStream.readLine();            

while (line != null) {                        

 workerName = line;

 line = inStream.readLine();               

 workerDepartment = line;

 line = inStream.readLine();               

 workerNumber = Integer.parseInt(line);

 }

 inStream.close();                  

“工作名称”

BufferedReader inStream= new BufferedReader 
(new InputStreamReader(TextArea.getText()));

String workerName = "";

String workerDepartment = "";

int workerNumber = 0;

String line = inStream.readLine();            

while (line != null) {                        

 workerName = line;

 line = inStream.readLine();               

 workerDepartment = line;

 line = inStream.readLine();               

 workerNumber = Integer.parseInt(line);

 }

 inStream.close();                  

“工部”

BufferedReader inStream= new BufferedReader 
(new InputStreamReader(TextArea.getText()));

String workerName = "";

String workerDepartment = "";

int workerNumber = 0;

String line = inStream.readLine();            

while (line != null) {                        

 workerName = line;

 line = inStream.readLine();               

 workerDepartment = line;

 line = inStream.readLine();               

 workerNumber = Integer.parseInt(line);

 }

 inStream.close();                  

“工作编号”

BufferedReader inStream= new BufferedReader 
(new InputStreamReader(TextArea.getText()));

String workerName = "";

String workerDepartment = "";

int workerNumber = 0;

String line = inStream.readLine();            

while (line != null) {                        

 workerName = line;

 line = inStream.readLine();               

 workerDepartment = line;

 line = inStream.readLine();               

 workerNumber = Integer.parseInt(line);

 }

 inStream.close();                  

如果行由任何分隔符分隔（例如换行符、逗号…），则使用String的split方法并放置分隔符

BufferedReader inStream= new BufferedReader 
(new InputStreamReader(TextArea.getText()));

String workerName = "";

String workerDepartment = "";

int workerNumber = 0;

String line = inStream.readLine();            

while (line != null) {                        

 workerName = line;

 line = inStream.readLine();               

 workerDepartment = line;

 line = inStream.readLine();               

 workerNumber = Integer.parseInt(line);

 }

 inStream.close();                  

String[] lines = TextArea.getText().split("\n");

//then you can access your array
String workerName = lines[0];
String workerDepartment = lines[1];
// and so on

此外，您还需要在获取值之前检查数组大小以防止ArrayOutOfIndexException，例如，如果只有两行，则不应调用行[2]，因此请执行以下检查：

BufferedReader inStream= new BufferedReader 
(new InputStreamReader(TextArea.getText()));

String workerName = "";

String workerDepartment = "";

int workerNumber = 0;

String line = inStream.readLine();            

while (line != null) {                        

 workerName = line;

 line = inStream.readLine();               

 workerDepartment = line;

 line = inStream.readLine();               

 workerNumber = Integer.parseInt(line);

 }

 inStream.close();                  

   if ( lines.length < 3 ) {
      // input is not complete, show error message
   }
   else {
      // do your splitting and reading values
   }

if（lines.length<3）{
//输入不完整，显示错误消息
}
否则{
//执行拆分和读取值的操作
}
