    Default doubts about boolean

    Hello folks,

    I have got this example here to develop in java JDK and run it on DCP,and I have some douts how to do it using the Boolean.

    Description

    Robert ( male ) is 10, Mary ( female ) is 25 and John ( male ) is 75
    Write a program that prints to the screen the information and a colour based on age and gender of each person:
    - Children ( age less or equal than 12 )
     Male: Light Blue
     Female: Light Pink
    - Adult ( age between 13 and 50 )
     Male: Blue
     Female: Red
    - Senior ( age greater 50 )
     Male: Green
     Female: White

    Output
    Robert ( Children - Male - 10 years old ) colour: Light Blue
    Mary.. ( Adult - Female - 25 years old ) colour: Red
    John.. ( Senior - Male - 75 years old ) colour: Green
    NOTE: The information about each person should come from variables !!! Do NOT hard code it !!!

    Thanks in advance for any help.

    Default Re: doubts about boolean

    Its the same syntax for most variables:
    THE_TYPE THE_VARIABLE_NAME
    optionally followed by = and an initial VALUE
    followed by ;

    The posted code does not have the variable names for the booleans.
    boolean variables can only have two values: true or false


    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
