2 store values
how to
store text values
program requirements
store
a text value into a
variable
and then
output
the value from the variable
learning-point
in Java a variable is
declared
before
it is used, it must also be given an initial value before being used for anything else
a variable to store a
text
value is declared as a
String
data type
a variable is declared
only once
but it must be declared
before
it is used for the first time
a
variable
-
name
is a word, but it does
not
use "speech marks"
it is good practice to assign an initial values to a variable when the variable is declared
introducing the code
1
String
ingredient
=
"zucchini"
;
2
System.out.println(ingredient);
understanding the code
on line 1 the ingredient variable is declared as String data-type because it will store text.
on line 1 the the variable called ingredient is also assigned an initial text value of "zucchini"
a variable must be declared
before
it can be assigned an initial value
on line 2 the value stored in the variable ingredient is output
The code above will produce this output in the console
zucchini
understanding the output
The value stored in the variable is displayed.
There are no speech marks output.
The name of the variable is not displayed, it does
not
output:
ingredient
develop the code
a program to store the names of ingredients and recipes and display output using the stored values
read the user interface design to see what the result should look like
read the code, run the code, (coding frame)
edit the code to complete part 1B, use part 1A to help, there are
//comments
in the coding frame to help you
create code to complete part 1C, details in the readme file in the repl project
user interface design
the final display for part A should look look this
Ingredient of the day is: cauliflower
Recipe idea: cauliflower rice
Recipe idea: cauliflower bread
