Wipro asks this question to determine your technical knowledge and understanding of Java—one of the most common programming languages. Example: “StringBuffer was developed before StringBuilder. StringBuffer is synchronized, so programs that use it take more memory and time to run. StringBuilder was developed as a drop-in replacement for StringBuffer. Since it is not synchronized, it is not thread-safe, so you can only use it where StringBuffer is used by a single thread. However, it is faster in most cases.”
