| Problem | | | | | Solution | Exercise extra caution when choosing a technique for string concatenation in Java programs. Simply using the '+=' operator to concatenate two strings creates a large number of temporary Java objects, since the Java String object is immutable. This can lead to poor performance (higher CPU utilization) since the garbage collector has additional objects to collect. Use the Java StringBuffer object to concatenate strings because it is more efficient. | |
