        System.out.format("%s, %s", "Hello", "world");

        System.out.println("\n---------------------------");

        float floatVar = 90.8f;
        int intVar = 100;
        String stringVar = "Peter";

        System.out
                .format("The value of the float variable is "
                        + "%f, while the value of the integer variable is %d, "
                        + "and the string is %s", floatVar, intVar,
                        stringVar);
