[Java기초] StringBuilder와 StringBuffer

StringBuilder
- Java에서 StringBuilder는 가변(mutable)한 문자열을 처리하기 위한 클래스.
- StringBuffer와 마찬가지로 새로운 문자열을 추가하거나 변경하게 되면 “기존의 객체”로 추가 및 변경이 된다.
- StringBuffer와 다르게 멀티쓰레드 환경에서 안정적이지 않으며, StringBuilder는 싱글쓰레드 환경에서 StringBuffer보다 더 빠른 성능을 가진다.

 

StringBuffer
- Java에서 StringBuffer는 가변(mutable)한 문자열을 처리하기 위한 클래스. 즉, 새로운 문자열을 추가하거나 변경하게 되면 “기존의 객체”로 추가 및 변경이 된다.
