아이디 중복검사

Path path = new Path();
			
String readPath = path.userPath+"userList.txt";
File file = new File(readPath);

while((line = reader.readLine()) != null) {
	String []info = line.split("■");
		if(info[0].indexOf(str) > -1) {	
				System.out.println("\t\t\t중복된 아이디가 존재합니다.");
					return false;

//유효성검사 통과

새롭게 가입이 되면 기초정보파일을 생성

String [] info = str.split("■");
readPath = path.userPath;

System.out.println(info[0]);
File newFile = new File(readPath+"userInfo\\"+info[0]+".txt");	//유저정보
newFile.createNewFile();
writer = new BufferedWriter(new FileWriter(newFile));
writer.write("B■500\n");//브론즈 0포인트 -> 새로 생성된 아이디이므로
writer.close();

newFile = new File(readPath+"userCoupon\\"+info[0]+".txt");	//쿠폰정보
newFile.createNewFile();
writer = new BufferedWriter(new FileWriter(newFile));
writer.write("discount3");//
writer.close();

newFile = new File(readPath+"userCard\\"+info[0]+".txt");	//카드정보
newFile.createNewFile();
writer = new BufferedWriter(new FileWriter(newFile));
writer.write("0");//브론즈 0포인트 -> 새로 생성된 아이디이므로
writer.close();
