Display Variables

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

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

Example

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

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

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

From the example above, you can expect:

  • x stores the value 5
  • y stores the value 6
  • Then we use the println() method to display the value of x + y, which is 11
