Final answer:
The statement is true; a String object is immutable, which means once it is created, its value cannot change. Any modification results in a new String object being created. This understanding is vital for efficient coding in languages like Java.
Step-by-step explanation:
The statement that a String object is immutable is indeed true. In programming, particularly when dealing with languages such as Java, when you create a String object, it cannot be modified. If you try to alter a String, a new String object is created with the new value, while the original object remains unchanged. This concept is critical to understand because it affects the performance and working of the code.
For example, if you concatenate two strings, what actually happens is a new String object is created that contains the combined value. The two original strings are not altered in this process. This is an essential aspect of the String class in Java and similar languages. Understanding this concept can help in writing more efficient and bug-free code.
