Pattern을 이용하여 문자열 중 pattern값을 인식하는 방식
Method
public String findNextStr(String input) throws IOException
{
String nextStr = null;
Pattern pattern = Pattern.compile("([a-z]+)+([0-9]+)");
Matcher pStartMatcher = pattern.matcher(input.toLowerCase());
while (pStartMatcher.find())
{
String strFull = pStartMatcher.group(0);
String strPart1 = pStartMatcher.group(1);
String strPart2 = pStartMatcher.group(2);
System.out.println(strFull);
System.out.println(strPart1);
System.out.println(strPart2);
nextStr = strPart1 + String.valueOf((Integer.valueOf(strPart2)+1));
}
return nextStr;
}
method 호출
public static void main(String[] args) throws IOException
{
ControllerMethod ctrl = new ControllerMethod();
String table = "AbcdefGHijk10002ADc";
String nextStr = null;
nextStr = ctrl.findNextStr(table);
System.out.println(nextStr);
}
실행결과
abcdefghijk10002
abcdefghijk
10002
abcdefghijk10003
코드는 쉬운데.. 개념을 처음 접하기엔 어렵네.ㅋㅋ
