or `substring(0,1)` if you want it as a String instead of a character – Thilo Sep 24 '14 at 07:06
Thanks mate, its perfect – user1710911 Sep 24 '14 at 07:10

this will throw an error if you do `textView.setText(test.charAt(0))` as it's a char not string. – Prabs Apr 28 '17 at 08:15
This is what @Thilo is trying to say: ` **String test = "StackOverflow"; String first = test.substring(0,1);**` – Collins USHI Apr 27 '20 at 00:09

Another way is

String test = "StackOverflow";
String s=test.substring(0,1);

In this you got result in String

You can refer this link, point 4.

public class StrDemo
{
public static void main (String args[])
{
    String abc = "abc";

    System.out.println ("Char at offset 0 : " + abc.charAt(0) );
    System.out.println ("Char at offset 1 : " + abc.charAt(1) );
    System.out.println ("Char at offset 2 : " + abc.charAt(2) );

  //Also substring method
   System.out.println(abc.substring(1, 2));
   //it will print

bc

// as starting index to end index here in this case abc is the string 
   //at 0 index-a, 1-index-b, 2- index-c

// This line should throw a StringIndexOutOfBoundsException
    System.out.println ("Char at offset 3 : " + abc.charAt(3) );
 }
}

Use charAt():

public class Test {
   public static void main(String args[]) {
      String s = "Stackoverflow";
      char result = s.charAt(0);
      System.out.println(result);
   }
}

Here is a tutorial
