在D:/a 下面創建100個txt文件 命名方式：學生信息001.txt 刪除編號是奇數文件

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

public class Test04 {

	public static void main(String[] args) throws IOException {
		// TODO Auto-generated method stub
		String path = "D:\\b\\學生信息";
		for (int i = 1; i <=100; i++) {
			String filename = path + formatName(i) + ".txt";
			File file = new File(filename);
			file.createNewFile();
		/*	if(i %2 != 0) {
				file.delete();
			}*/
		}
	}
	public static String formatName(int i) {
		if(i<10) {
			return "00" + i;
		}else if(i<100) {
			return "0" + i;
		}else {
			return "" +i;
		}
	}
}
