Java解释Excel数据（jxl.jar包的使用）
基本操作
一、创建文件
拟生成一个名为“测试数据.xls”的Excel文件，其中第一个工作表被命名为“第一页”，大致效果如下：
/*
* Created on Dec 30, 2007
*
* To change the template for this generated file go to
* Window>Preferences>Java>Code Generation>Code and Comments
*/
package JExcelTest.standard;
import java.io.*;
import jxl.*;
import jxl.write.*;
/**

*/
public class CreateXLS {
public static void main(String[] args) {
try {
//open file.
WritableWorkbook book = Workbook.createWorkbook(new File("d:/Test.xls"));
//create Sheet named "Sheet_1". 0 means this is 1st page.
WritableSheet sheet = book.createSheet("Sheet_1", 0);
//define cell column and row in Label Constructor, and cell content write "test".
//cell is 1st-Column,1st-Row. value is "test".
Label label = new Label(0, 0, "test");
//add defined cell above to sheet instance.
sheet.addCell(label);
//create cell using add numeric. WARN:necessarily use integrated package-path, otherwise will be throws path-error.
//cell is 2nd-Column, 1st-Row. value is 789.123.
jxl.write.Number number = new jxl.write.Number(1, 0, 789.123);
//add defined cell above to sheet instance.
sheet.addCell(number);
//add defined all cell above to case.
book.write();
//close file case.
book.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
编译执行后，会�
相关文档：
create PROCEDURE pagelist
@tablename nvarchar(50),
@fieldname nvarchar(50)='*',
@pagesize int output,--每页显示记录条数
@currentpage int output,--第几页
@orderid nvarchar(50),--主键排序
@sort int,--排序方式，1表示升序，0表示降序排列

package Demo;
// 使用泛型统一传入的参数类型
class Info28<T> {
private T var; // 此类型由外部决定
public T getVar() {
return this.var;
}
public void setVar(T var) {
this.var = var;
}
public String toString() { // 覆写Object类中的toString()方法
return this.var.toString();

package Demo;
// Java泛型的嵌套设置
class Info31<T, V> { // 接收两个泛型类型
private T key;
private V value;
public Info31(T key, V value) {
this.setKey(key);
this.setValue(value);
}
public void setKey(T key) {
this.key = key;
}
public void setValue(V value) {

导入配置jar包 substance.jar
然后在frame的主函数 加入如下代码
JFrame.setDefaultLookAndFeelDecorated(true);
JDialog.setDefaultLookAndFeelDecorated(true);
try {
UIManager.setLookAndFeel(new org.jvnet.substance.skin.SubstanceModerateLookAndFeel()) ; ......
下面的例子，就是使用ObjectSNMP获取RFC1213-MIB的例子：其中的system和ifTable对象就是对应的SNMP MIB中的system组合interface中的ifTable表。
class TestMibMapping
{
SNMPAPI snmpapi;
SNMPNodeParam nodeParam;
public TestMibMapping()
{
try
{
/**
