Convert a String to an Array
There are many ways to convert a string to an array. The simplest way is to use the toCharArray() method:
charExplanation: The method toCharArray() turns the string into an array of characters. Each letter of "Hello" becomes one element in the array, so myArray[0] is H .
You can also loop through the array to print all array elements:
Example
// Create a string String myStr = "Hello"; // Convert the string to a char array char[] myArray = myStr.toCharArray(); // Print array elements
for (char i : myArray) {
System.out.println(i);
}Explanation: The loop goes through each element in the array and prints it. So for "Hello" , it prints the letters one by one: H, e, l, l, o.
