converting .txt to excel format using java

I know the logic.It involves reading the text file using fileinputstream,datainputstream,buffered reader.By creating array list and store those line in array list.By creating a workbook,sheet,row and cell, set the values for each column cell.using iterator split the line and assign it to each column cell.set the splitted values to column cell.using the fileoutputstream write the values in the excel sheet. But because of lack in syntax i'm unable to code.
