Java How To Convert a String to an Array

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:

Example

Convert a string to a char array:

// Create a string
String myStr = "Hello";

// Convert the string to a char array
char[] myArray = myStr.toCharArray();

// Print the first element of the array
System.out.println(myArray[0]);

Explanation: 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.
