VeganPizza

Report a typo

You've decided to cook a vegan pizza and now you need to perform the following steps in the right order (like in the sample output). Correct the mistake in the program and cook your pizza!

Note: go through these classes to understand the code better.

class Base extends Thread {    
    @Override
    public void run() {
        System.out.println("cook base");
    }
}

class Tomatoes extends Thread {
    @Override
    public void run() {
        for (int i = 3; i >= 1; i--) {
            System.out.println("slice tomatoes " + i);
        }
    }
}

class Tofu extends Thread {
    @Override
    public void run() {
        System.out.println("fry tofu");
    }
}
class Bake extends Thread{
    @Override
    public void run() {
        for (int i = 4; i >= 0; i--) {
            if (i == 0) {
                System.out.println("Your pizza is ready!");
                break;
            }
            System.out.println("to bake..." + i + " min");

        }
    }
}

Write a program in Java 17
class Pizza {

//Fix this method

stepOfCook.add(base);
stepOfCook.add(tomatoes);
stepOfCook.add(tofu);
stepOfCook.add(bake);
for (Thread step : stepOfCook) {
step.start();
}
}

//Don't change the code below
static class Base extends Thread {
@Override

System.out.println("cook base");
}
}
