Question

I need help with my code. It keeps getting this error:

The assignment is:

Food.java:28: error: method getName in class Food cannot be applied to given types; return String.format ("Food - name: %10s | calories: %4d", this.getName(), this required: String found: no arguments reason: actual and formal argument lists differ in length Food.java:28: error: method getCalories in class Food cannot be applied to given types; return String.format("Food - name: %10s | calories: $4d", this.getName(), this required: int found: no arguments reason: actual and formal argument lists differ in length Food.java:39: error: method getName in class Food cannot be applied to given types; return name == food.getName() && required: String found: no arguments reason: actual and formal argument lists differ in length Food.java:40: error: cannot find symbol calories == food.getCalories; symbol: variable getCalories location: variable food of type Food 4 errors

Create a class to represent a Food object. Use the description provided below in UML.

Food

• name : String

• calories : int

• Food(String, int) // The only constructor. Food name and calories must be

// specified

• setName(String) : void // Sets the name of the Food

• getName() : String // Returns the name of the Food

• setCalories(int) : void // Sets the calories of the Food

• getCalories() : int // Returns the calories of the Food

• toString() : String @Override //see Note1:

• equals(Object) : boolean @Override //see Note2:

NOTE1:

toString() method returns a String with the following format:

“Food - name: %10s | calories: %4d”

NOTE2:

Two instances of Food are equal if, and only if, their names are equal and their calories are equal.

My code is:

import java.util.*;
public class Food {
   private String name;
   private int calories;
  
   public Food (String name, int calories) {
       this.setName(name);
       this.setCalories(calories);
   }
  
   public String setName (String name) {
       this.name = name;
   }
  
   public int setCalories (int calories) {
       this.calories = calories;
   }
  
   public String getName (String name) {
       return this.name;
   }
  
   public int getCalories (int calories) {
       return this.calories;
   }

   public String toString(){
       return String.format("Food - name: %10s | calories: %4d",this.getName(),this.getCalories());
   }
  
   public boolean equals(Object other){
       if (this == other) {
           return true;
       }
       if (other == null || getClass() != other.getClass()) {
           return false;
       }
       Food food = (Food) other;
       return name == food.getName() &&
       calories == food.getCalories;
   }
}

Please help and thank you!

public class Food {
   private String name;
   private int calories;
  
   public Food (String name, int calories) {
       this.setName(name);
       this.setCalories(calories);
   }
  
   public String setName (String name) {
       this.name = name;
   }
  
   public int setCalories (int calories) {
       this.calories = calories;
   }
  
   public String getName () {
       return this.name;
   }
  
   public int getCalories () {
       return this.calories;
   }

   public String toString(){
       return String.format("Food - name: %10s | calories: %4d", this.getName(), this.getCalories());
   }
  
   public boolean equals(Object other){
       if (this == other) {
           return true;
       }
       if (other == null || getClass() != other.getClass()) {
           return false;
       }
       Food food = (Food) other;
       return name.equals(food.getName()) && (calories == food.getCalories());
   }
}
