Question
Consider the below statements. Statement 1 : Matcher class interprets the pattern in a StringStatement 2 : Matcher class matches the regular expression against the text provided Which of the following is true?Select one:a.Both Statement 1 and 2 are incorrect.b.Statement 1 alone is correct.c.Both Statement 1 and 2 are correctd.Statement 2 alone is correct.
Solution
c. Both Statement 1 and 2 are correct
Explanation: In Java, the Matcher class is used to interpret the pattern and match the regular expression against the text provided. So, both statements are correct. The Matcher class interprets the pattern in a string and matches the regular expression against the text provided.

Problem StatementBob loves playing a string-matching game where he tries to match two strings based on a specific pattern. In this game, players input two strings, and the game determines whether they match according to a set of rules. Here are the rules of the game:A '*' in the first string represents zero or more characters.A '?' in the first string represents exactly one character.Any other character in the first string must match the corresponding character in the second string.Bob has requested your assistance in completing the game mentioned above.Input format :The first line of input consists of a string str1 containing the characters along with the symbols - ? and *.The second line consists of the string str2, without any symbols.Output format :The first line displays the "Second string: " followed by str2 as string, representing the second input string.The second line displays the following format:"The strings match" if the first string matches the second according to the pattern rules."The strings do not match" if the first string does not match the second according to the pattern rules.Refer to the sample output for the formatting specifications.Code constraints :In the given scenario, the test cases fall under the following constraints:2 ≤ length of the string (str1, str2) ≤ 15Sample test cases :Input 1 :i?mneoiamneoOutput 1 :Second string: iamneoThe strings matchInput 2 :i?miaamOutput 2 :Second string: iaamThe strings do not matchInput 3 :i*mn?oiaamneoOutput 3 :Second string: iaamneoThe strings matchInput 4 :a?b?c?d?e?f?ghaxbxcydzefffghOutput 4 :Second string: axbxcydzefffghThe strings matchInput 5 :a*cacOutput 5 :Second string: acThe strings matchNote :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.
