Java MCQ: Which of the following is not a method in the ‘String’ class?
a) length()
b) substring()
c) equalsIgnoreCase()
d) size()
Answer:
d) size()
Explanation:
The Java String class provides a variety of methods for manipulating and inspecting strings. Common methods include length() for getting the length of the string, substring() for extracting a portion of the string, and equalsIgnoreCase() for comparing strings while ignoring case differences.
However, size() is not a method in the String class. The correct method for obtaining the length of a string is length(). Using size() would result in a compilation error.
Familiarity with the methods available in the String class is essential for effectively working with string data in Java.
