The syntax of this line is wrong:
这一行的语法是错误的：
Workbook wrk1=new Workbook.getWorkbook("C:\Test.xls");
you are trying to use newon a static method of the Workbookclass. The correct syntax is:
您正在尝试new在Workbook类的静态方法上使用。正确的语法是：
Workbook wrk1 = Workbook.getWorkbook("C:\Test.xls");
(no newkeyword)
（无new关键字）

There are two ways of creating workbooks in JExcel. Both require Fileobjects.
在 JExcel 中有两种创建工作簿的方法。两者都需要File对象。
A non-writable workbook:
不可写的工作簿：
Workbook workbook = Workbook.getWorkbook(new File("D:\file2.xls"));
or by creating a writable workbook with
或者通过创建一个可写的工作簿
WritableWorkbook writableWorkbook = Workbook.createWorkbook(new File("D:\file1.xls"));
Workbook itself is an abstract class that allows different method with different return types (WritableWorkbooks and Workbooks).
Workbook 本身是一个抽象类，它允许具有不同返回类型（WritableWorkbooks 和 Workbooks）的不同方法。
getWorkbookand createWorkbookare use the Factory Pattern
getWorkbook并且createWorkbook使用工厂模式
