Initialising objects

CaoimH_in

Hi all, wonder if you could help me with this?

I'm trying to compile this:

public class SortSoftwareProject
{
public static void main(String[] args)
{
SoftwareProject[] aProject = new SoftwareProject[6];
aProject[0] = new SoftwareProject("IBM", 'D', 'M');
aProject[1] = new SoftwareProject("Microsoft", 'C', 'M');
aProject[2] = new SoftwareProject("Apple", 'Q', 'L');
aProject[3] = new SoftwareProject("Intel", 'C', 'L');
aProject[4] = new SoftwareProject("Me", 'S', 'D');
aProject[5] = new SoftwareProject("You", 'M', 'Q');
bubbleSort(aProject);
for(int i = 0; i < aProject.length; i++)
System.out.print(aProject.getCustomerName());
}

And this is the class I created.

public class SoftwareProject
{
private String custName;
private char projName;
private char serType;
private double projCost = 10000;


public void SoftwareProject(String inputName, char inputProjectName, char serviceTypeName)
{
custName = inputName;
projName = inputProjectName;
serType = serviceTypeName;
}

public char getProjectName()
{
return projName;
}

public char getServiceType()
{
return serType;
}

public String getCustomerName()
{
return custName;
}

public double getProjectCost()
{
return projCost;
}
}

Basicly, creating an array of projects to be bubble sorted by customer name.

I have the method for the bubble sort, but I'm getting this compilation error:

required: no arguments
found: String,char,char
reason: actual and formal argument lists differ in length
SortSoftwareProject.java:11: error: constructor SoftwareProject in class Softwar
eProject cannot be applied to given types;
aProject[5] = new SoftwareProject("You", 'M', 'Q');
^
required: no arguments
found: String,char,char
reason: actual and formal argument lists differ in length
SortSoftwareProject.java:22: error: constructor SoftwareProject in class Softwar
eProject cannot be applied to given types;
temp = new SoftwareProject("word", 'a', 'b');
^

Anyone spot what I'm doing wrong?

Constructors should not have a return type, i.e. within the SoftwareProject class

public void SoftwareProject(String inputName, char inputProjectName, char serviceTypeName)
{
custName = inputName;
projName = inputProjectName;
serType = serviceTypeName;
}

should read

public SoftwareProject(String inputName, char inputProjectName, char serviceTypeName)
{
custName = inputName;
projName = inputProjectName;
serType = serviceTypeName;
}

Because of the return type, you only actually have a default constructor with no arguments available, and as the error says, this can't be applied to an argument list.

public class SortSoftwareProject
{
public static void main(String[] args)
{
SoftwareProject aProject = new SoftwareProject();
aProject = new SoftwareProject("IBM", 'D', 'M');
aProject = new SoftwareProject("Microsoft", 'C', 'M');
aProject = new SoftwareProject("Apple", 'Q', 'L');
aProject = new SoftwareProject("Intel", 'C', 'L');
aProject = new SoftwareProject("Me", 'S', 'D');
aProject = new SoftwareProject("You", 'M', 'Q');
bubbleSort(aProject);
for(int i = 0; i < aProject.length; i++)
System.out.print(aProject.getCustomerName());
}

Are you trying to sort a single variable? Don't think that was what the OP was looking for..... You might as well rewrite yours as the below:

public class SortSoftwareProject
{
public static void main(String[] args)
{
SoftwareProject aProject = new SoftwareProject();
aProject = new SoftwareProject("You", 'M', 'Q');
bubbleSort(aProject);
for(int i = 0; i < aProject.length; i++)
System.out.print(aProject[i].getCustomerName());
}

And I still think you'll get the same compile error for the reason I posted above
