print class with multiple arguments

Question

I'm a newbie to Java. Can you tell me why I can't print a proper result of this code?

    public Main() {
    Pizza pizza = new Pizza("yes", "Cheese", 20000);
    System.out.println(pizza);
}

I have created the class pizza like this.

package pitjahat;

public class Pizza {
private String name;
private String topping;
private Integer price;

public Pizza(String name, String topping, Integer price) {
    super();
    this.name = name;
    this.topping = topping;
    this.price = price;
}

public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getTopping() {
    return topping;
}
public void setTopping(String topping) {
    this.topping = topping;
}
public Integer getPrice() {
    return price;
}
public void setPrice(Integer price) {
    this.price = price;
}
}

and the result that comes out when I run is like this

pitjahat.Pizza@52af6cff

You need to create a `toString()` method in the Pizza class for println to be able to print it properly — Nosrep, Oct 22 '20 at 12:45

You have to override/implement the toString() method in your Pizza class.

If you use Intellij IDEA you can use the Alt + Insert combo to generate the method by the intellij. (Or Right click -> Generate...)

In eclipse Right click -> Source -> Generate toString()
