Concatenation

String Concatenation

Concatenation in Java involves combining strings using the ‘+’ operator.

Example

String firstName = "John";
String lastName = "Doe";
System.out.println(firstName + " " + lastName);

Note that we’ve included an empty string (” “) to insert a space between firstName and lastName when printing.

Another method to concatenate two strings is by using the concat() method:

Example

String firstName = "John ";
String lastName = "Doe";
System.out.println(firstName.concat(lastName));
