Java创建文件夹与创建文件

// author: [email][e-mail][/email]
// description: 程序先检查文件夹是否存在,如果不存在,则创建一个,存在,则继续运行.
// 文件夹处理完成后,下一步工作为往文件夹中创建文件.
// caution: 当前文件夹中如果已经有名为abc.txt的文件时,
// 在当前文件夹创建一个名为abc.txt的文件会失败.
// 在这个程序中,如果E://test 下已经有名为1,2,3,4的文件时,程序执行会失败.


import java.io.*;

public class Demo
{
public static void main( String[] args)
{
File dirFile;
File tempFile;
boolean bFile;
String sFileName;

bFile = false;

try
{
dirFile = new File("E://test");
bFile = dirFile.exists();

if( bFile == true )
{
System.out.println("The folder exists.");
}
else
{
System.out.println("The folder do not exist,now trying to create a one...");
bFile = dirFile.mkdir();
if( bFile == true )
{
System.out.println("Create successfully!");
}
else
{
System.out.println("Disable to make the folder,please check the disk is full or not.");
System.exit(1);

System.out.println("Now we put files in to the folder...");

for(int i=0; i<5; i++)
