Java Print Variables - Using println() and Concatenation

Learn how to print variables in Java using the println() method. Combine text with variables efficiently using the + operator for output in your Java programs.

Java Print Variables

The println() method in Java is used to display variables.

To combine text and a variable, use the + character:

Example:

String name = "John";
System.out.println("Hello " + name);

String name = "John";
System.out.println("Hello " + name);

Hello John

You can also concatenate variables together using the + operator:

Example:

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

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

John Doe

For numeric values, the + character functions as a mathematical operator:

Example:

int x = 5;
int y = 6;
System.out.println(x + y); // Print the value of x + y

int x = 5;
int y = 6;
System.out.println(x + y);
