我正在寻找一个包含字符串’Total’的电子表格中的单元格,然后使用该单元格所在的行来查找另一个单元格中的总值,该单元格始终是相同的单元格/列(0中的第10个单元格)基于索引).
我有以下代码,没有错误(语法),但findCell方法没有返回rowNum值:
public static void main(String[] args) throws IOException{ String fileName = "C://file-path//report.xls"; String cellContent = "Total"; int rownr=0, colnr = 10; InputStream input = new FileInputStream(fileName); HSSFWorkbook wb = new HSSFWorkbook(input); HSSFSheet sheet = wb.getSheetAt(0); rownr = findRow(sheet, cellContent); output(sheet, rownr, colnr); finish(); } private static void output(HSSFSheet sheet, int rownr, int colnr) { /* * This method displays the total value of the month */ HSSFRow row = sheet.getRow(rownr); HSSFCell cell = row.getCell(colnr); System.out.println("Your total is: " + cell); } private static int findRow(HSSFSheet sheet, String cellContent){ /* * This is the method to find the row number */ int rowNum = 0; for(Row row : sheet) { for(Cell cell : row) { while(cell.getCellType() == Cell.CELL_TYPE_STRING){ if(cell.getRichStringCellValue().getString () == cellContent);{ rowNum = row.getRowNum(); return rowNum; } } } } return rowNum; } private static void finish() { System.exit(0); } }
此方法修复是您的问题的解决方案:
private static int findRow(HSSFSheet sheet, String cellContent) { for (Row row : sheet) { for (Cell cell : row) { if (cell.getCellType() == Cell.CELL_TYPE_STRING) { if (cell.getRichStringCellValue().getString().trim().equals(cellContent)) { return row.getRowNum(); } } } } return 0; }
请记住,您的colnr仍然是固定值.
