1.獲取表格中name列的值效果：
[game_loginwith, game_guest, game_policy, game_loading, game_main_played, game_main_pkgames, game_main_battleroom, game_main_roombutton, game_main_gamebutton, game_main_instantgame, game_main_moregames, game_main_bottom, game_main_loadfail, game_main_playbtn, game_matching, game_waitingtime, game_matchsucceed, game_matchfailed, game_matchtryagain, game_resultwin, game_resultlose, game_resultagain, game_resultchange, game_result_bubble, game_result_askbutton, game_result_acceptbtn, game_result_leftbtn, game_neterror, game_retrybtn, game_timeout, game_battle_open, game_battle_enter, game_battle_roomtitle, game_battle_choose, game_create_slogan, game_room_num, game_room_waiting, game_room_getout, game_room_outbtn, game_room_staybtn, game_enter_title, game_enter_tip, game_enter_invalid, game_battle_slogan, game_enter_success, game_banner_setting, game_banner_share, game_banner_login, game_feedback_title, game_feedback_question, game_queston_bug, game_question_advice, game_question_others, game_question_detail, game_contact_info, game_contact_tip, game_submit_btn, game_submit_tip, game_contact_email, game_contact_whats, game_contact_messenger, game_contact_line, game_contact_way, game_ok_btn, game_cancel_btn, game_setting_policy, game_aboutus, game_logout]
2.獲取表格中第一行的值：
[Login With, 登入方式, 登入方式, , , , , , , , , , , , , , , , , , , , ]3.讀取表格行列的值：
行：69 列：24 name EN rev zh-rTW zh-rCN removed duplicate duplicate_name Owner 使用場景或功能名稱 字元限制 order game_loginwith Login With 登入方式 登入方式 game_guest Guest 遊客 遊客 game_policy By signing up, you agree to our User Agreement & Privacy Policy 登入即同意使用者協議與隱私 登入即同意使用者協議與隱私 game_loading Loading... 載入中 載入中 game_main_played Recently Played Games 最近玩過的遊戲 最近玩過的遊戲 game_main_pkgames 1V1 Games 1V1對戰遊戲 1V1對戰遊戲 game_main_battleroom Battle Rooms 對戰間 對戰間 game_main_roombutton GO NOW Go Now Go Now game_main_gamebutton PLAY NOW 立即開始 立即開始 game_main_instantgame Instant Games 單機遊戲 單機遊戲 game_main_moregames More 更多遊戲 更多遊戲 game_main_bottom Stay tuned 敬請期待 敬請期待 game_main_loadfail Loading failed, please retry. 遊戲載入失敗，請重試 遊戲載入失敗，請重試 game_main_playbtn PLAY 開始遊戲 開始遊戲 game_matching Matching 匹配中 匹配中 game_waitingtime Waiting for %s S 已等待%s 秒 已等待%s 秒 game_matchsucceed Succesfully Matched 匹配成功 匹配成功 game_matchfailed Matching Failed 匹配失敗 匹配失敗
4.將獲取到的值寫入到TXT或者xls中
import java.io.File; import java.io.FileInputStream; import java.io.FileWriter; import java.io.IOException; import java.io.InputStream; import java.io.PrintWriter; import java.util.ArrayList; import jxl.Cell; import jxl.Sheet; import jxl.Workbook; import jxl.read.biff.BiffException; public class Excel { public static void main(String[] args) { try { //獲取指定列的值 readSpecifyColumns(new File("D:\\wenan\\111.xls")); //獲取指定行的值 readSpecifyRows(new File("D:\\wenan\\111.xls")); //讀取行列的值 readRowsAndColums(new File("D:\\wenan\\111.xls")); //將獲取到的值寫入到TXT或者xls中 copy_excel(new File("D:\\wenan\\111.xls")); } catch (Exception e) { e.printStackTrace(); } } /** * 讀取指定列 * @param file * @throws Exception */ public static void readSpecifyColumns(File file)throws Exception{ ArrayList<String> columnList = new ArrayList<String>(); ArrayList<String> valueList = new ArrayList<String>(); Workbook readwb = null; InputStream io = new FileInputStream(file.getAbsoluteFile()); readwb = Workbook.getWorkbook(io); Sheet readsheet = readwb.getSheet(0); int rsColumns = readsheet.getColumns(); //獲取表格列數 int rsRows = readsheet.getRows(); //獲取表格行數 for (int i = 1; i < rsRows; i++) { Cell cell_name = readsheet.getCell(0, i); //第一列的值 columnList.add(cell_name.getContents()); Cell cell_value = readsheet.getCell(2, i); //第三列的值，此處需要手動更改，獲取不同列的值 valueList.add(cell_value.getContents()); } System.out.println(columnList); System.out.println(valueList); String[] name_String = new String[columnList.size()]; String[] value_String = new String[columnList.size()]; for (int i = 0; i < columnList.size(); i++) { name_String[i] = columnList.get(i); value_String[i] = valueList.get(i); // System.out.println("<string name=" + "\"" + name_String[i] + "\">" + value_String[i] + "</string>"); } } /** * 讀取指定行 * @param file * @throws Exception */ public static void readSpecifyRows(File file)throws Exception{ ArrayList<String> columnList = new ArrayList<String>(); Workbook readwb = null; InputStream io = new FileInputStream(file.getAbsoluteFile()); readwb = Workbook.getWorkbook(io); Sheet readsheet = readwb.getSheet(0); int rsColumns = readsheet.getColumns(); //獲取表格列數 int rsRows = readsheet.getRows(); //獲取表格行數 for (int i = 1; i < rsColumns; i++) { Cell cell_name = readsheet.getCell(i, 1); //在這裡指定行，此處需要手動更改，獲取不同行的值 columnList.add(cell_name.getContents()); } System.out.println(columnList); } private static void readRowsAndColums(File file) throws BiffException, IOException { //1:建立workbook Workbook workbook=Workbook.getWorkbook(new File("D:\\wenan\\111.xls")); //2:獲取第一個工作表sheet Sheet sheet=workbook.getSheet(0); //3:獲取資料 System.out.println("行："+sheet.getRows()); System.out.println("列："+sheet.getColumns()); for(int i=0;i<sheet.getRows();i++){ for(int j=0;j<sheet.getColumns();j++){ Cell cell=sheet.getCell(j,i); System.out.print(cell.getContents()+" "); } System.out.println(); } //最後一步：關閉資源 workbook.close(); } /** * 將獲取到的值寫入到TXT或者xls中 * @param file * @throws Exception */ public static void copy_excel(File file) throws Exception { FileWriter fWriter = null; PrintWriter out = null; String fliename = file.getName().replace(".xls", ""); fWriter = new FileWriter(file.getParent()+ "/agetwo.xls");//輸出格式為.xls fWriter = new FileWriter(file.getParent() + "/" + fliename + ".txt");//輸出格式為.txt out = new PrintWriter(fWriter); InputStream is = new FileInputStream(file.getAbsoluteFile()); Workbook wb = null; wb = Workbook.getWorkbook(is); int sheet_size = wb.getNumberOfSheets(); Sheet sheet = wb.getSheet(0); for (int j = 1; j < sheet.getRows(); j++) { String cellinfo = sheet.getCell(0, j).getContents();//讀取的是第二列資料，沒有標題，標題起始位置在for迴圈中定義 out.println(cellinfo); } out.close();//關閉流 fWriter.close(); out.flush();//重新整理快取 System.out.println("輸出完成！"); } }
