一个从xls中读取数据写入ArrayList的例子
public ArrayList<ProjInfo> getProjInfo(String filename){
ArrayList<ProjInfo> projs = new ArrayList<ProjInfo>();
File proj_xls = new File(this.filename);
Workbook wb = null;
try {
wb = Workbook.getWorkbook(proj_xls);
} catch (BiffException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Sheet ws = wb.getSheet(0);
int row_num = ws.getRows();
int col_num = ws.getColumns();
int key_col = -1;
int pname_col = -1;
int status_col = -1;
int updated_col = -1;
for (int i=0; i< row_num; i++){
if ((-1 == key_col)||(-1 == pname_col)||(-1 == status_col)||(-1 == updated_col)){
for (int j=0; j<col_num; j++){
String cell_content = ws.getCell(j,i).getContents();
if(cell_content.contentEquals("Key")){
key_col = j;
}else if (cell_content.contentEquals("Summary")){
pname_col = j;
}else if (cell_content.contentEquals("Status")){
status_col = j;
}else if (cell_content.contentEquals("Updated")){
updated_col = j;
}
}
}else{
ProjInfo pi = new ProjInfo();
pi.setKey(ws.getCell(key_col, i).getContents());
pi.setProjname(ws.getCell(pname_col, i).getContents());
pi.setStatus(ws.getCell(status_col,i).getContents());
pi.setUpdated(ws.getCell(updated_col, i).getContents().split("\\s")[0]);
if (! pi.getKey().isEmpty()){
projs.add(pi);
}
}
}
return projs;
}
