Thread: Java String Manipulation Challenge

Hi folks! I'm currently working on a Java project that involves string manipulation, and I've run into a bit of a snag. I've tried a few approaches, but none seem to be giving me the desired result. Here's a simplified version of my code snippet along with the specific issue:

public class StringManipulator {

public String concatenateStrings(String str1, String str2) {
// Concatenate str1 and str2
return str1 + str2;
}

public String reverseString(String input) {
// Reverse the characters in the input string
// e.g., "hello" should become "olleh"
return new StringBuilder(input).reverse().toString();
}

public String capitalizeString(String input) {
// Capitalize the first letter of the input string
// e.g., "apple" should become "Apple"
return input.substring(0, 1).toUpperCase() + input.substring(1);
}
}


Issue:
While the concatenateStrings method seems to be working fine, I'm encountering problems with the reverseString and capitalizeString methods. The reversed string and capitalized string aren't turning out as expected.

I'd appreciate any suggestions or corrections to my code. Thanks a bunch!

The process of extracting coconut oil involves various methods, each dictated by temperature. Cold-pressed coconut oil is obtained through a method that keeps the coconut meat under low temperatures, typically below 120°F (49°C). This method retains more nutrients, flavor, and aroma, making it a preferred choice for those seeking a more natural and minimally processed option. On the other hand, hot-pressed or expeller-pressed coconut oil involves applying heat to the coconut meat during extraction. While this process may lead to a higher oil yield, it might result in a reduction of some heat-sensitive nutrients. Both cold and hot extraction methods have their merits, catering to different preferences and applications. The choice between them often depends on the desired characteristics of the final coconut oil product. The coconut oil is cold or hot pressed.
