Java String Concatenation
Strings can be joined together by using the + operator. We refer to this as concatenation:
Example
String firstName = "John";
String lastName = "Doe";
System.out.println(firstName + " " + lastName);
Observe that in order to provide a space between firstName and lastName while printing, we have added an empty text (” “).
Example
String firstName = "John ";
String lastName = "Doe";
System.out.println(firstName.concat(lastName));
