9.5: Displaying Strings

  • You can put as many statements as you like in main. For example, to display more than one line of output:

    public class Hello {
    
        public static void main(String[] args) {
            // generate some simple output
            System.out.println("Hello, World!"); // first line
            System.out.println("How are you?"); // another line
        }
    }
    

    Phrases that appear in quotation marks are called strings, because they contain a sequence of “characters” strung together. Characters can be letters, numbers, punctuation marks, symbols, spaces, tabs, etc.

    System.out.println appends a special character, called a newline, that moves to the beginning of the next line. If you don’t want a newline at the end, you can use print instead of println:

    public class Goodbye {
    
        public static void main(String[] args) {
            System.out.print("Goodbye, ");
            System.out.println("cruel world");
        }
    }
    

    In this example, the first statement does not add a newline, so the output appears on a single line as Goodbye, cruel world. Notice that there is a space at the end of the first string, which appears in the output.
