Program Name: DataCenterCostAnalysis.java

Virtual Cloud Unlimited (VCU) is a cloud computing startup that manages data centers to sell to other companies. VCU has created a text file of their data center cost data that we looked at in Project 2. You will write a program that will accept at the command line two filenames: one is a text file containing the data center cost data and the other is an output filename.

The data in the first text file consists of information about the data centers that VCU manages. The data contains many lines of data, one for each data center. Each line of data contains information about a data center:

The construction firm building the data center

The construction cost of the data center (in millions of dollars)

The IT load of the data center (in megawatts)

The operating cost of the data center (in millions of dollars)

A sample text file is below:

Certainly! Below is the implementation of the `DataCenter.java` class based on the specifications provided:

```java
public class DataCenter {
    // Instance variables
    private String constructionFirm;
    private double constructionCost;
    private double ITLoad;
    private double operatingCost;

// Default constructor
    public DataCenter() {
        this.constructionFirm = "";
        this.constructionCost = 0.0;
        this.ITLoad = 0.0;
        this.operatingCost = 0.0;
    }

// Parameterized constructor
    public DataCenter(String constructionFirm, double constructionCost, double ITLoad, double operatingCost) {
        this.constructionFirm = constructionFirm;
        this.constructionCost = constructionCost;
        this.ITLoad = ITLoad;
        this.operatingCost = operatingCost;
    }

// Getters
    public String getConstructionFirm() {
        return constructionFirm;
    }

public double getConstructionCost() {
        return constructionCost;
    }

public double getITLoad() {
        return ITLoad;
    }

public double getOperatingCost() {
        return operatingCost;
    }

// Setters
    public void setConstructionFirm(String constructionFirm) {
        this.constructionFirm = constructionFirm;
    }

public void setConstructionCost(double constructionCost) {
        this.constructionCost = constructionCost;
    }

public void setITLoad(double ITLoad) {
        this.ITLoad = ITLoad;
    }

public void setOperatingCost(double operatingCost) {
        this.operatingCost = operatingCost;
    }

// toString() method
    @Override
    public String toString() {
        return String.format("%s %.2f %.2f %.2f",
                constructionFirm,
                constructionCost,
                ITLoad,
                operatingCost);
    }
}
```

### Explanation:
- The class defines four private instance variables as specified.
- The default constructor initializes string to empty and doubles to 0.0.
- The parameterized constructor allows setting all variables at object creation.
- Getters and setters are provided for each variable.
- The `toString()` method formats the output with two decimal places for the double values, aligning with the requirement to round to two decimal places.

---

### Next Steps:
You can now proceed to implement the `DataCenterCostAnalysis.java` class that will utilize this `DataCenter` class to read data from a file, process it, and write results to an output file as per your project requirements.

If you'd like, I can help you with that implementation as well!
