Java Output / Print

Print Text

You learned from the previous chapter that you can use the println() method to output values or print text in Java:

Example

            System.out.println("Hello World!");
        

You can add as many println() methods as you want. Note that it will add a new line for each method:

Example:

System.out.println("Hello World!");
System.out.println("I am learning Java.");
System.out.println("It is awesome!");
        

Double Quotes

When you are working with text, it must be wrapped inside double quotations marks "".

If you forget the double quotes, an error occurs:

Example

System.out.println("This sentence will work!");

System.out.println(This sentence will produce an error);

The Print() Method

There is also a print()method, which is similar to println().

The only difference is that it does not insert a new line at the end of the output:

Example

System.out.print("Hello World! ");
System.out.print("I will print on the same line.");
        

Note that we add an extra space (after "Hello World!" in the example above), for better readability.

Java Output Numbers

You can also use the println() method to print numbers.

However, unlike text, we don't put numbers inside double quotes:

Example

System.out.println(3);
System.out.println(358);
System.out.println(50000);
        

You can also perform mathematical calculations inside the println() method:

Example

System.out.println(3 + 3);

System.out.println(2 * 5);
