Madali lang naman sya.
Gamitan mo nalang ng magkahiwalay na array yung fruits at price (in order dapat)
Tas gamitan mo nalang ng algorithms dun sa pagcompute ng total price depending on the quantity with the tax.

Code:
import java.util.HashMap;
import java.util.Scanner;

class Main {
  static void start() {
    // Clear Screen
    System.out.print("\033[H\033[2J"); 
    System.out.flush();

    Scanner input = new Scanner(System.in);

    //PRINT Available Fruits
    System.out.println("Available Fruits:");
    System.out.println("a. Apple (15.75)");
    System.out.println("b. Banana (19.25)");
    System.out.println("c. Chico (5.95))");
    System.out.println("d. Durian (152.35)");

    //Store Price
    HashMap<String, String> FruitsAndPrices = new HashMap<String, String>();;
    FruitsAndPrices.put("a", "15.75");
    FruitsAndPrices.put("b", "19.25");
    FruitsAndPrices.put("c", "5.95");
    FruitsAndPrices.put("d", "152.35");

    //Ask User
    System.out.println("Enter fruit code:");
    String selectedFruit = input.nextLine();

    //If selectedFruit is out of choice re run
    if(null == FruitsAndPrices.get(selectedFruit)){
      System.out.println("Invalid Code");
      start();
    }else{
      System.out.println(FruitsAndPrices.get(selectedFruit));
    }
  }
  public static void main(String[] args) {
    start();
  }
}

ikaw na mag tuloy tinamad ako🤣

para sa mga makakabasa nito : di ako pro.. first time lang ako sa java pero may unting back ground ako sa python kaya mga pro pag pasensyahan nyo na ako kung madumi😅

Ituloy nyo napo haha para sa grade maraming salamat po
 
take nyo na binigay ni boss jayvee, mapasa at magkapoints ka man sa assignment na yan, at the end of the day ikaw ang mahihirapan kaya dapat pagaralan mo yan. Also, medyo complex na yan sa tingin ng walang background sa programming kaya imposible na ibigay ng prof nyo yan ng hindi kayo tinuturuan.
