I am not gonna give you the code but you can achieve what you want using the steps below:

Get the first charcter from the string using String#charAt(0)
Use Character#toUpperCase to convert it into uppercase
concatenate the result back to the original string

String str = "abcd";
Character first = Character.toUpperCase(str.charAt(0));
str = first + str.substring(1, str.length());
System.out.println(str);  //Will print Abcd

This code

Gets the first Character from the String
Converts it to upper case (using Character.toUpperCase(char ch))
Concatenate the first letter (that was changed to upper case) with the rest of the String

I don't like to use the + operator for concatenating strings, consider using concat method (or StringBuilder in case you want to concatenate more strings..)
