In this tutorial, we will learn to iterate through each characters of the string.
Example 1: Loop through each character of a string using for loop
class Main { public static void main(String[] args) { // create a string String name = "Programiz"; System.out.println("Characters in " + name + " are:"); // loop through each element for(int i = 0; i<name.length(); i++) { // access each character char a = name.charAt(i); System.out.print(a + ", "); } } }
Output
Characters in Programiz are: P, r, o, g, r, a, m, i, z,
In the above example, we have used the for-loop to access each element of the string. Here, we have used the charAt() method to access each character of the string.
Example 2: Loop through each character of a string using for-each loop
class Main { public static void main(String[] args) { // create a string String name = "Programiz"; System.out.println("Characters in string \"" + name + "\":"); // loop through each element using for-each loop for(char c : name.toCharArray()) { // access each character System.out.print(c + ", "); } } }
Output
Characters in string "Programiz": P, r, o, g, r, a, m, i, z,
In the above example, we have converted the string into a char array using the toCharArray(). We then access each element of the char array using the for-each loop.
