How to get char value of a string at a specified position?

The chartAt() method of the String class returns the char value at the specified index. An index ranges from 0 to length() - 1. If we specified an index beyond of this range a StringIndexOutOfBoundsException exception will be thrown.

These method use zero based index which means the first char value of the sequence is at index 0, the next at index 1, and so on, as for array indexing.

public class CharAtExample {
    public static void main(String[] args) {
        String[] colors = {

        int index = 3;
        for (String color : colors) {
            // Get char value of a string at index number 3. Because
            // the index is zero based we'll get the fourth character
            // of each color in the array.
            char value = color.charAt(index);
            System.out.printf("The fourth char of %s is '%s'n",
                    color, value);


Here is the program output:

The fourth char of black is 'c'
The fourth char of white is 't'
The fourth char of brown is 'w'
The fourth char of green is 'e'
The fourth char of yellow is 'l'
The fourth char of blue is 'e'
