  1. In Topic: use of HashSet and ICollection for foreign key relationship in classes

    Posted 19 Apr 2015

    I know that HashSet is used to get the unique members. ICollection is used when iterate among our classes using a foreach loop and also for count property.
    But why need to use = new HashSet<course>(); in the constructor and ICollection for the property.
  2. In Topic: pattern search

    Guys here is the attachment for my question. Sorry for the inconvenience.

    My code is this, but it is not working.

    import os,re

    fileName_path = input ("Please input the file name with location: ")
    directory = os.path.dirname(fileName_path)
    fileName = os.path.basename(fileName_path)
    oF = open(fileName ,"r")
    with oF as readFile:    
        for searchpattern in readFile:        
            cnt ="tempCharSearch[\s]:[\s]= [\s]\'[\d]-[\d]-[\d]\'",searchpattern,re.IGNORECASE)
            if cnt:
                print (cnt)
  3. In Topic: get input via a class and and use the input in another class

    Posted 8 Jan 2014

    When I remove radius parameter from
    float getRadius = ui1.GetInput(radius);

    I get the following error.

    The method GetInput(float) in the type UserInterface is not applicable for the
    arguments ()

    What is this error?

    Thank you for the quick reply. Ive some confusions though.

    I tried to go with your reply but can not make up to the outputs.

    Please can you help with the code.

    package set_01_14_pkg;
    import java.util.Scanner;

    public class UserInterface 
          float radius;
    	  Scanner in = new Scanner(;
    	public float GetInput(float radius)
    		System.out.println("Enter the radius of the circle");
    		rad = in.nextFloat();
    		return rad;		

    public class GetResult {
    	public static void main(String[] args)
    		UserInterface ui1 = new UserInterface();		
    		float getRadius = ui1.GetInput(radius); // [b]getting error radius cannot be resolved[/b]
    		System.out.println(" radius "+ getRadius);

    getting the error: radius cannot be resolved
    How to pass the value of the radius to the Circle CLASS to calculate the area too.

    can you please reply me how can I do it?
