java读写excel文件代码如下:

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;

import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
import jxl.write.Label;
import jxl.write.WritableCellFormat;
import jxl.write.WritableFont;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;

public class Excel {
/**
*
* @Description：读取excel文件
* @param filePath
* @throws Exception: 返回结果描述
* @return void: 返回值类型
* @throws
*/
public void readExcel(String filePath) throws Exception{

int row=st.getRows();
int col=st.getColumns();
for (int i = 0; i < row; i++) {
for (int j = 0; j < col; j++) {
Cell cell=st.getCell(j, i);
String content=cell.getContents();
System.out.print(content + "\t");
}
System.out.println();
}
wb.close();
is.close();
}
