In this example, we choose to implement the same code using the str.at() function in C++ which we implement using the charAt() function in Java. Again, a “Testing CharAt” string is created and the str.at() function is implemented to get the character at index 0, 5, and 8 which ...
Syntax: char String.charAt(index); It accepts anindexand returns the characters from the specified position of theString. Note:If the index is out of range, the method returns"String index out of range"exception. Example: Input: str = "includeHelp" Function call: str.charAt(0) Output: "...
Another String method, startsWith(), can be confused with the function of charAt(0). The difference lies in the result of either method: charAt(0) will return a character, whereas startsWith() is a test, returning a boolean. Thankfully, it’s very unlikely that you will be expected to...
