It took a long time to practice jxl, Today, let's also remember the key points .
jxl Mainly java Used for operation excel Of . Can be excel Read out the contents in , You can also write something to excel in .
Both reading and writing are very similar . The main classes when reading are : WritableWorkBook( Its instance object is created through static methods : WorkBook.createWorkBook(), Arguments can be files , Output stream When reading, it should be a file ); Sheet class ( It is equivalent to a table in the document , adopt WritableWorkBook Instance createSheet() Method instantiation .) Next is reading, needless to say .
When writing operations :WritableWorkBook( Its instance object is created through static methods : WorkBook.createWorkBook(), Arguments can be files , Output stream When writing, it should be the output stream ); WritableSheet class ( It is equivalent to a table in the document , adopt WritableWorkBook Instance createSheet() Method instantiation .), The next step is to write , Needless to say .
