The method you're looking for is charAt. Here's an example:
String text = "foo";
char charAtZero = text.charAt(0);
System.out.println(charAtZero); // Prints f
For more information, see the Java documentation on String.charAt. If you want another simple tutorial, this one or this one.
If you don't want the result as a char data type, but rather as a string, you would use the Character.toString method:
String text = "foo";
String letter = Character.toString(text.charAt(0));
System.out.println(letter); // Prints f
If you want more information on the Character class and the toString method, I pulled my info from the documentation on Character.toString.

You want .charAt()
Here's a tutorial
"mystring".charAt(2)
returns s
If you're hellbent on having a string there are a couple of ways to convert a char to a string:
String mychar = Character.toString("mystring".charAt(2));
Or
String mychar = ""+"mystring".charAt(2);
Or even
String mychar = String.valueOf("mystring".charAt(2));
For example.

Like if I am passed "Wed" I want to know that it is index 2.

You could use an ArrayList and its indexOf(Object) method https://docs.oracle.com/javase/8/docs/api/java/util/ArrayList.html#indexOf-java.lang.Object- which returns the int index of the first occurrence of the object in the list, in this case all objects are unique so it would work. Although under the hood it is simply looping: /** * Returns the lowest index at which element appears in this List, or * -1 if it does not appear. * * @param e the element whose inclusion in the List is being tested * @return the index where e was found */ public int indexOf(Object e) { for (int i = 0; i < size; i++) if (equals(e, data[i])) return i; return -1; } https://developer.classpath.org/doc/java/util/ArrayList-source.html
