? Convert a String to Character Array in Java

Java provides many ways to convert a `String` to `char` Array (`char[]`). A `String` can be converted to a `char` Array in several ways. The most straightforward method is to use the `toCharArray()` method of the `String` class. This method returns a `char[]` array which is a copy of the characters in the `String`. Another approach is to loop through each character of the `String` and assign it to the corresponding index of the `char` array. The third approach is to use the `StringReader` class which provides a method called `read()` which reads the `String` into a character array. The fourth approach is to use the `getChars()` method of the `String` class which reads a sequence of characters into a character array. Finally, the last approach is to use the `StringBuffer` class which provides a method called `getChars()` which reads a sequence of characters into a character array. In this article, we will discuss the different ways of converting a `String` to a `char` Array in Java. We will discuss the various methods available, their advantages and disadvantages, and provide code examples for each.

Algorithm: 1. Create an empty character array. 2. Loop through the string and copy each character to the character array. 3. Return the character array. Sample Code: ``` public static char[] convertStringToCharArray(String input) { char[] charArray = new char[input.length()]; for (int i = 0; i < input.length(); i++) { charArray[i] = input.charAt(i); } return charArray; } ```
