Question

Consider the below statements.

Statement 1: Matcher class interprets the pattern in a string.
Statement 2: Matcher class matches the regular expression against the text provided.
Which of the following is true?
a. Statement 1 alone is correct.
b. Both statements 1 and 2 are correct.
c. Statement 2 alone is correct.
d. Both statements 1 and 2 are incorrect.

Answer 1

The correct answer is option c, Statement 2 alone is correct. The Matcher class does not interpret the pattern; it matches the compiled pattern (from the Pattern class) against the provided text.

Step-by-step explanation:

The given statements are related to the Matcher class in Java, which is used in conjunction with the Pattern class to perform regular expression operations. Let's analyze each statement:

• Statement 1: Matcher class interprets the pattern in a string. This statement is not completely accurate. The Matcher class doesn't interpret the pattern; the Pattern class is responsible for compiling the regular expression itself into a pattern. Once compiled, the Matcher class is used to perform matching operations against a sequence of characters, typically a string.
• Statement 2: Matcher class matches the regular expression against the text provided. This statement is correct. The primary function of the Matcher class is indeed to match the compiled regular expression pattern against the provided text.

Therefore, option c, Statement 2 alone is correct, is the accurate answer.
