How to display Variables?

Display Variables

The println() method is often used to display variables.

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

Example

String name = “Jane”;

System.out.println(“Hello ” + name);

You can also use the ‘+’ character to add a variable to another variable:

Example                                                        

String firstName = “Jane ”;

String lastName = “Doe”;

String fullName = firstName + lastName;

System.out.println(fullName);

For numeric values, the + character works as a mathematical operator (notice that we use int (integer) variables here):

Example

int x = 5;

int y = 6;

System.out.println(x + y); // Print the value of x + y

From the above example, you can expect:

• x stores the value 6
• y stores the value 7
• Then we use the println() method to display the value of x + y, which is 13

Declare Many Variables

To declare more than one variable of the same type, use a comma-separated list:

Example

int x = 5, y = 6, z = 50;

System.out.println(x + y + z);
