Do you plan to use the StringBuilder class to optimize string concatenation operations to avoid creating new objects?

Yes, using StringBuilder in Java is recommended for optimizing string concatenation operations, especially in loops or when performing many operations. It helps avoid creating multiple intermediate String objects, as StringBuilder modifies the content within a single object. Example:

StringBuilder sb = new StringBuilder();
for (int i = 0; i < 10; i++) {
    sb.append(i).append(", ");
}
String result = sb.toString();
