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();
}
}
}
