问题描述
我试图读取使用Apache POI在Java中的Excel文件，但是，Eclipse中没有编译code。
I tried to read an excel file using apache poi in java, however, Eclipse did not compile the code.
public class ReadExcel {
public static void main(String[] args) throws IOException {
FileInputStream file = new FileInputStream(new File("C:\\Users\\XXXXXXXXXXXXXXXXal\\042012.xls"));
HSSFWorkbook wb = new HSSFWorkbook(file);
HSSFSheet sheet = wb.getSheetAt(0);
Iterator<Row> rowIterator = sheet.iterator();
while (rowIterator.hasNext()) {
Row row = rowIterator().next(); \\ THIS LINE GETS UNDERLINED BY ECLIPSE!!!
Iterator<Cell> cellIterator = row.cellIterator();
while(cellIterator.hasNext()) {
Cell cell = cellIterator.next();
System.out.print(cell.getStringCellValue() + "\t\t");
}
}
file.close();
FileOutputStream out =
new FileOutputStream(new File("C:\\test.xls"));
wb.write(out);
out.close();
}
}
Eclipse中始终强调鳞次栉比= rowIterator（）和Next（）; 行。我不知道为什么？我怎么能提高呢？
Eclipse always underlines Row row = rowIterator().next(); line. I do not know why? How can I improve it?
推荐答案
问题是不是日食，它与code。你不能把rowIterator其是可变的，作为一种方法。你不能调用与（）语法的变量。
The problem is not with eclipse, it is with the code. You can not treat rowIterator which is a variable, as a method. You can not invoke a variable with the () syntax.
试试这个：
public static void main(String[] args) throws IOException {
FileInputStream file = new FileInputStream(new File("C:\\Users\\XXXXXXXXXXXXXXXXal\\042012.xls"));
HSSFWorkbook wb = new HSSFWorkbook(file);
HSSFSheet sheet = wb.getSheetAt(0);
Iterator<Row> rowIterator = sheet.iterator();
while (rowIterator.hasNext()) {
Row row = rowIterator.next();
Iterator <Cell> cellIterator = row.cellIterator();
while (cellIterator.hasNext()) {
Cell cell = cellIterator.next();
System.out.print(cell.getStringCellValue() + "\t\t");
}
}
file.close();
FileOutputStream out =
new FileOutputStream(new File("C:\\test.xls"));
wb.write(out);
out.close();
}
