So sánh hiệu suất của String và StringBuilder trong Java

When working with strings in Java, understanding the differences between String and StringBuilder is crucial for writing efficient and optimized code. While both handle textual data, their underlying implementations lead to significant performance differences, especially when dealing with string manipulation operations.

Choosing between String and StringBuilder depends on the specific requirements of your Java program. For simple operations or when immutability is desired, String remains a suitable choice. However, when dealing with frequent string manipulations or large datasets, StringBuilder offers significant performance advantages. By understanding the strengths and weaknesses of each, developers can make informed decisions to optimize their code for efficiency and maintainability.
