Function of jxl.jar in java

Hi all What is the main function of jxl.jar in java...does JExcelApi has any connection with jxl.java T开发者_开发技巧hanks in advance.

jxl.jar is the library of JExcelApi , which is a open source java API to read, write, and modify Excel spreadsheets dynamically. It contains all the compiled *.class files, associated metadata and resources that are used by the Java Excel API internally .

Java library are distributed as a .jar file .You can refer to this for more info about JAR.

As the official API of JExcelApi does not contain a file called jxl.java .I believe this is the Java class created by you to test the function of JExcelApi . To use the JExcelApi , you have to import the necessary classes from the jxl.jar and specified jxl.jar to be on the class path when you compile jxl.java .

So , the connection between jxl.java and jxl.jar is that jxl.java calls the classes from jxl.jar to manipulate the Excel.
