Considering memory usage and performance, what is the impact of using += for string concatenation in a loop?
- += creates a new string object in each iteration, leading to high memory usage and poor performance.
- += is optimized by the Java compiler, resulting in low memory usage and good performance.
- += is suitable for small string concatenations but not recommended for large-scale operations.
- += is the same as using StringBuilder and is always the best choice for string concatenation.
Using += for string concatenation in a loop can have a significant impact on memory usage and performance. It creates a new string object in each iteration, leading to increased memory consumption and reduced performance, especially for large-scale operations. It is not optimized by the Java compiler, unlike using StringBuilder, which is more efficient for concatenating strings in a loop.
