Question
Assume s is "ABCABC", the method _____ returns a new string "aBCaBC".A. s.toLowerCase(s)B. s.replace('A', 'a')C. s.replace('a', 'A')D. s.replace("ABCABC", "aBCaBC")
Solution 1
The correct answer is B. s.replace('A', 'a'). This method will replace all occurrences of 'A' in the string s with 'a', resulting in "aBCaBC".
Solution 2
The correct answer is B. s.replace('A', 'a')
Here is the step by step explanation:
- We have a string s = "ABCABC"
- We need to replace 'A' with 'a' in the string s.
- The method s.replace('A', 'a') does exactly this. It scans the string for the character 'A' and replaces it with 'a'.
- So, after the replacement, the new string becomes "aBCaBC".
Therefore, option B is the correct answer.
