i cannot make it work,,

What do you mean by you can't make it work? Can you compile it? If not, what's the error messages? And please post code using the CODE tags.

[NormR1]

Also what is it supposed to do?

[djenoe]

i'm trying to run Admin class using methods from Property class
i can't add property to the
Array , idon't know where to store the property array, i can't access the array.

[djenoe]

it's an Array of Objects,, Property (String ID, String description, String loc,
double weekly rate)
do i store the array in property class or Admin class
i can't access it..
Thanx mate

[NormR1]

Do you get any error messages when you compile or execute the code? Please copy and paste them here. See previous posts on this topic.

[javaAddict]

properties is an array. It doesn't have these methods:
printPropertyDetails, addProperty.
For printing loop the array and take each Property object from the array and print that.
As for adding you need to do what you do at the beginning of your program. You have the count variable. So add the next property there and increase it:

if (num == 1) {
  if (count<properties.length) {
    properties[count] = new Property("ID", "description", "location", 0.0);
    count++;
  } else {
    System.out.println("properties is full");
  }
}

thank you java addict..
is it alright to store my array of objects in admin class?? main method,
and use the methods from property class to perform( whatever)

thanx everyone..

[djenoe]

post code using the CODE tags. what do you mean code tags??
is it //comments ?
thanx mate

[NormR1]

The rightmost icon above the input window showing: [ code ] will put code tags around the selected code.

properties.addProperty("ID", "description", "location", 0.0);

The properties variable shown above is an array, not a class with a method called addProperty(). What class has the method: addProperty()?
Does the Property class have that method?
You need to use an index to get to an element in the properties array. The elements of the property array are of type Property.
properties[ix] // Get the Property object at the ix position in the array
