Question
this is the problem/ someone tried to help me with this already but sent it back with even more errors/ using bluejay
After a long and tedious journey of helping Alexander and Elizabeth we feel we’ve done our part in helping and plan to get on the road in the morning. Our bags were packed and set at the edge of the bed waiting for us to awake, but when we wake up our bags are missing! It seems thieves came in through the open window last night and stole our belongings. Before we can get back on the road we need to gather some money in order to purchase new equipment. To help raise money we have talked to a local shop owner and he mentioned that he liked Alexander’s flower pack, but would like it to hold more than just flowers. The new flower pack should hold plants which can be flowers, fungus or weed. • Create a plant class that has three child classes (flower, fungus and weed). o Each subclass shares certain qualities (ID and Name) § The ID should be something the program creates such as a sequential number; the user should not be asked to indicate the ID o Flower traits include (Color, Thorns, and Smell) o Fungus traits include (Color and Poisonous) o Weed traits include (Color, Poisonous, Edible and Medicinal) • All items should be able to be displayed. • Be able to add, remove, search and filter these plants – by name. • For traits that are Yes or No such as “Is the Weed Poisonous?” – consider using Booleans. Don’t use a string for all traits. • Submit 5 files: Final.java, Flower.java, Fungus.java, Plant.java and Weed.java
