String objects have a lot of methods that can be called, one of which is charAt
, which accepts a number as the index value into the string.
String fruit = "Apple";
fruit.charAt(0); // 'A'
Reference: Oracle Java Docs - String
Also, Craig provides a really good tip that characters can be compared using >
and <
.
if ('a' < 'b') {
System.out.println("Yep, 'a' comes before 'b'");
}
