1 Iterate over Characters in String using For Loop

In this example,

We create a string named str with a value of "Java".
We use a for loop with an index variable i to iterate over the string length.
Within the loop, we use charAt(i) method to access each character at index i.
Finally, we print each character to the console.

Java Program

public class Main {
    public static void main(String[] args) {
        String str = "Java";
        for (int i = 0; i < str.length(); i++) {
            System.out.println(str.charAt(i));
        }
    }
}

Output

J
a
v
