Java简易qq聊天，代码

这种东西，除非是网络上原本就有的。否则你几乎要不到的，即使是简易版想做出来，除非是高手，起码要一个星期。

怎么用java下载qq邮箱中文件存储在本地

一.读取Excel文件内容

复制代码代码如下:

/** *//**读取Excel文件的内容

* @param file 待读取的文件

* @return

*/

public static String readExcel(File file)...{

StringBuffer sb = new StringBuffer();

Workbook wb = null;

try ...{

//构造Workbook（工作薄）对象

wb=Workbook.getWorkbook(file);

} catch (BiffException e) ...{

e.printStackTrace();

} catch (IOException e) ...{

e.printStackTrace();

}

if(wb==null)

return null;

//获得了Workbook对象之后，就可以通过它得到Sheet（工作表）对象了

Sheet[] sheet = wb.getSheets();

if(sheet!=nullsheet.length0)...{

//对每个工作表进行循环

for(int i=0;isheet.length;i++)...{

//得到当前工作表的行数

int rowNum = sheet[i].getRows();

for(int j=0;jrowNum;j++)...{

//得到当前行的所有单元格

Cell[] cells = sheet[i].getRow(j);

if(cells!=nullcells.length0)...{

//对每个单元格进行循环

for(int k=0;kcells.length;k++)...{

//读取当前单元格的值

String cellValue = cells[k].getContents();

sb.append(cellValue+" ");

}

}

sb.append(" ");

}

sb.append(" ");

}

}

//最后关闭资源，释放内存

wb.close();

return sb.toString();

}

二.写入Excel文件

这里有很多格式了，比如文本内容加粗，加上某些颜色等，可以参考jxl的api

复制代码代码如下:

/**生成一个Excel文件

* @param fileName 要生成的Excel文件名

*/

public static void writeExcel(String fileName)...{

WritableWorkbook wwb = null;

try ...{

//首先要使用Workbook类的工厂方法创建一个可写入的工作薄(Workbook)对象

wwb = Workbook.createWorkbook(new File(fileName));

} catch (IOException e) ...{

e.printStackTrace();

}

if(wwb!=null)...{

//创建一个可写入的工作表

//Workbook的createSheet方法有两个参数，第一个是工作表的名称，第二个是工作表在工作薄中的位置

WritableSheet ws = wwb.createSheet("sheet1", 0);

//下面开始添加单元格

for(int i=0;i10;i++)...{

for(int j=0;j5;j++)...{

//这里需要注意的是，在Excel中，第一个参数表示列，第二个表示行

Label labelC = new Label(j, i, "这是第"+(i+1)+"行，第"+(j+1)+"列");

try ...{

//将生成的单元格添加到工作表中

ws.addCell(labelC);

} catch (RowsExceededException e) ...{

e.printStackTrace();

} catch (WriteException e) ...{

e.printStackTrace();

}

}

}

try ...{

//从内存中写入文件中

wwb.write();

//关闭资源，释放内存

wwb.close();

} catch (IOException e) ...{

e.printStackTrace();

} catch (WriteException e) ...{

e.printStackTrace();

}

}

}
