charAt(int index):Get a single char by index

To extract a single character from a String, you can refer directly to an individual character via the charAt( ) method.

char charAt(int index)
Returns the char value at the specified index.

public class Main {
  public static void main(String[] argv) {
    byte[] bytes = new byte[]{67,68,69}; 
    
    String str = new String(bytes);
    
    System.out.println(str.charAt(0));
  }
}
