String Concatenation

The + operator can be used between strings to combine them. This is called concatenation:

Example

String firstName = "John";

String lastName = "Doe";

System.out.println(firstName + " " + lastName);

Note that we have added an empty text (" ") to create a space between firstName and lastName on print.

You can also use the concat() method to concatenate two strings:

Example

String firstName = "John ";

String lastName = "Doe";

System.out.println(firstName.concat(lastName));
