Week 6: Methods of OO Programming/04. Fish within permitted limits

Once upon a time there was a fishing competition. 
In the category 'FishMeasurements', the minimum and maximum length and weight of fish allowed in the competition are defined as category variables.

The 'Fish' class models a single fish. 
The class has attributes length and weight.
For the Fish class, write the public method  

public boolean allowed()

which returns true or false depending on whether the given Fish object is within the allowed limits in a competition.






import java.util.Random;
public class Test{
    public static void main(String[] args){
        final Random rnd = new Random();
        
        
        System.out.println("Testing the method allowed...");
        
        for (int i=0; i<10; i++){
            Fish fish = new Fish(rnd.nextInt(80) + 10, rnd.nextInt(7) + rnd.nextDouble());
            System.out.println("" + fish);
            System.out.println(fish.allowed() ? "Allowed" : "Not allowed");
        }
        
    }
}


class FishMeasurements{
    public static final int MINIMUM_LENGTH = 25;
    public static final int MAXIMUM_LENGTH = 75;
    public static final double MINIMUM_WEIGHT = 1.0;
    public static final double MAXIMUM_WEIGHT = 5.0;
}


class Fish{
    private int length;
    private double weight;
    
    public Fish(int length, double weight){
        this.length = length;
        this.weight = weight;
    }



    // ADD
    public boolean allowed() {
        boolean allowed = false;
        if (this.length >= FishMeasurements.MINIMUM_LENGTH && 
            this.length <= FishMeasurements.MAXIMUM_LENGTH && 
            this.weight >= FishMeasurements.MINIMUM_WEIGHT && 
            this.weight <= FishMeasurements.MAXIMUM_WEIGHT) {
            allowed = true;
        }
        
        return allowed;
    }


    
    
    public String toString(){
        return "Length:" + length + ", weight:" + weight;
    }
}
