Which of the following determines whether two different String objects contain the same string?
Understand the Problem
The question is asking about how to compare two String
objects in a programming language (likely Java, based on the terminology). It wants to know which operator or method correctly checks if the two String
objects have the same content, not if they are the same object in memory.
Answer
The `equals` method.
The equals
method determines whether two different String objects contain the same string.
Answer for screen readers
The equals
method determines whether two different String objects contain the same string.
More Information
In Java, the ==
operator checks if two String references point to the same object in memory. The .equals()
method, on the other hand, compares the actual content of the strings, returning true if they contain the same sequence of characters.
Tips
A common mistake is using ==
to compare the content of strings. This only checks if the references are the same, not if the strings have the same value. Always use .equals()
to compare String content.
