創建一個文件d:/a/b/c/haha.xls 10秒後將這個文件刪除 Thread.sleep(10*1000)

import java.io.File;
import java.io.IOException;

public class Test02 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		File dir = new File("D:/a/b/c");
		if(!dir.exists()) {
			dir.mkdirs();
		}
		
		File file = new File("D:/a/b/c/haha.xls");
		
		try {
			System.out.println(file.createNewFile());
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		
		try {
			Thread.sleep(10*1000);
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
		
		file.delete();
	}

}
