public class Product {

private Integer productId;
private String productName;
private String productDesc;

private double productPrice;


public Integer getProductId() {
return productId;
}


public void setProductId(Integer productId) {
this.productId = productId;
}


public String getProductName() {
return productName;
}


public void setProductName(String productName) {
this.productName = productName;
}


public String getProductDesc() {
return productDesc;
}


public void setProductDesc(String productDesc) {
this.productDesc = productDesc;
}


public double getProductPrice() {
return productPrice;
}


public void setProductPrice(double productPrice) {
this.productPrice = productPrice;
}


@Override
public String toString() {
return "Product [productId=" + productId + ", productName="
+ productName + ", productDesc=" + productDesc
+ ", productPrice=" + productPrice + "]";
}

public String save(){
System.out.println("save: " + this);
return "details";
}

public String test(){
System.out.println("test");
return "success";
}

public Product() {
System.out.println("Product's constructor...");
}

}
