Question

Create an Asset class.

Assets have an asset ID, name, value, and sku (stock keeping unit) number.

Create a constuctor that accepts asset ID, name, value, and sku.

Create second constructor that accepts only name, value, and sku and creates a asset ID number that is one greater in value than the last asset ID used (or 100 if no previous asset ID was used).

Add a save method that stores the contents of an asset object to a text file named based on the assetID for that object. You must use printf to store the asset information in a comma separated format.

It should output something like:

Hi,

Please see the class below:

Thanks

Asset.java

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;

// Asset class
public class Asset {
   //Member variables asset ID, name, value, and sku (stock keeping unit) number.
   private static String asset_ID;
   private String name;
   private double value;
   private String sku;
   //constuctor that accepts asset ID, name, value, and sku.
   public Asset(String asset_ID, String name, double value, String sku) {
       super();
       this.asset_ID = asset_ID;
       this.name = name;
       this.value = value;
       this.sku = sku;
   }
   //constuctor that accepts asset ID, name, value, and sku.
   public Asset(String name, double value, String sku) {
       super();
       //asset ID number that is one greater in value than the last asset ID used (or 100 if no previous asset ID was used).
       if(null == getAsset_ID() || "".equalsIgnoreCase(getAsset_ID())){
           this.asset_ID = "100";
       }
       else{
           this.asset_ID = getAsset_ID() +1;
       }
       this.asset_ID = asset_ID;
       this.name = name;
       this.value = value;
       this.sku = sku;
   }
   /**
   * save method that stores the contents of an asset object to a text file named based on the assetID for that object
   */
   public void save(){
       FileWriter fw = null;

       String content = this.getAsset_ID()+","+this.getName()+","+this.getValue()+","+this.getSku();

       try {

           BufferedWriter bw = null;
           fw = new FileWriter(this.getAsset_ID()+".txt");
           bw = new BufferedWriter(fw);
           bw.write(content);
           bw.flush();

       } catch (IOException e) {

           e.printStackTrace();

       }
   }
   public String getAsset_ID() {
       return asset_ID;
   }
   public void setAsset_ID(String asset_ID) {
       this.asset_ID = asset_ID;
   }
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public double getValue() {
       return value;
   }
   public void setValue(double value) {
       this.value = value;
   }
   public String getSku() {
       return sku;
   }
   public void setSku(String sku) {
       this.sku = sku;
   }

}

SampleMain_Asset.java

public class SampleMain_Asset {

  
   public static void main(String [] args){
       //Creating an Asset object with asset ID, name, value, and sku.
       Asset asset = new Asset("100012", "table saw",100.12, "982342");
       asset.save();

       //Creating an Asset object with name, value, and sku.
       //Asset_ID will be automatically assigned
       Asset assetNew = new Asset( "table",160.10, "6342874");
       assetNew.save();
      
   }
}

Sample output:

100012.txt

100012,table saw,100.12,982342

1000121.txt

1000121,table,160.1,6342874
