.equals is a built in method for the String type.
String a = "Hello"; String b = "Hello";
a.equals(b); //Returns true
When comparing two Strings, use .equals rather than ==
String s4 = new String("Hello"); // String object String s5 = new String("Hello"); // String object
s4 == s5; // false, different pointers in heap s4.equals(s5); // true, same contents
== checks if the object points to the same pointer in memory, so if you want to see if two strings have the same content, use the built in .equals method.
