In Java, String and StringBuffer are both used to handle sequences of characters, but they differ significantly in mutability, thread-safety, and performance.
String objects are immutable — once created, their value cannot be changed. Any modification like concatenation results in the creation of a new object, which can lead to higher memory usage and slower performance for frequent changes. Example:
String str = "Hello";str.concat(" World"); // Creates a new String objectSystem.out.println(str); // Output: Helloコピーしました。✕コピーStringBuffer, on the other hand, is mutable — you can modify its content without creating new objects. It is also thread-safe because all its methods are synchronized, making it suitable for multi-threaded environments. Example:
StringBuffer sb = new StringBuffer("Hello");sb.append(" World"); // Modifies the same objectSystem.out.println(sb); // Output: Hello Worldコピーしました。✕コピーKey Differences:
