Iterate through Each Character of the String in Java

public class Iterate {
    public static void main(String[] args) {
        String name = "CodeOfCode";
        System.out.println("Characters in " + name + " are:");

        // iterating through each element
        for(int i = 0; i<name.length(); i++) {
            char a = name.charAt(i);
            System.out.print(a + ", ");
        }
    }
}

Characters in CodeOfCode are:                                                                                                 
C, o, d, e, O, f, C, o, d, e, 

• In this program, firstly a variable named name has been initialized.
• Then a for loop is executed which runs till the end of name variable’s length.
• Inside this loop, every character in name is fetched through charAt() method.
• The fetched character is then printed on the screen with a comma next to it.

public class Iterate {
    public static void main(String[] args) {
        String name = "CodeOfCode";
        System.out.println("Characters in string \"" + name + "\":");

        // using for-each loop to iterate through each element
        for(char ch : name.toCharArray()) {
            System.out.print(ch + ", ");
        }

    }
}

Characters in string "CodeOfCode":
 C, o, d, e, O, f, C, o, d, e, 

• In this program, firstly a variable named name has been initialized.
• Next, a for-each loop executes which first converts the variable name into a character array using toCharArray() method.
• Thus each character from name is retrieved and printed on the screen with a comma following it.
• This process continues till all the characters in name have been traversed.
