使用java读取execel

需要下载jxl.jar，去官网下载

代码如下：

//import java.io.*;
//import java.util.Scanner;
//
///**
// * @author Administrator
// * @version 1.0
// * @Date 2011-06-07 java练习
// */
//public class Test7 {
//
// /**
//  * 主函数
//  *
//  * @param args
//  */
// public static void main(String[] args) throws Exception {
//
//  Test7 test7 = new Test7();
//  test7.print();
//  test7.print1();
// }
//
// /**
//  * 计算并输出1-1000中所有偶数的和
//  *
//  * @throws IOException
//  */
// public void print() throws IOException {
//  int cn = 0;
//  for (int i = 1; i < 1000; i++) {
//   if (i % 2 == 0) {
//    cn += i;
//   }
//  }
//  System.out.println(cn);
// }
//
// /**
//  * 输出杨辉三角
//  */
// public void print1() {
//  Scanner sc = new Scanner(System.in);
//  System.out.println("请输入行数：");
//  int n = sc.nextInt();
//  int a[][] = new int[n][n];
//  int i, j;
//  for (i = 0; i < n; i++) {
//   a[i][i] = new Integer(1);
//   a[i][0] = new Integer(1);
//  }
//  for (i = 2; i < n; i++) {
//   for (j = 1; j <= i - 1; j++)
//    a[i][j] = a[i - 1][j - 1] + a[i - 1][j];
//  }
//  for (i = 0; i < n; i++) {
//   for (j = 0; j <= i; j++)
//    System.out.printf("%6d", a[i][j]);
//   System.out.println();
//  }
// }
//}
