I think nakapag gawa na ako nyan sa java dati,
Naka loop na if else lang tapos, nilagyan ko nalang ng A,B,C,D yung mga name ng items para madali lang e if else. Then yung answer na variable is naka auto UPPERCASE para kahit ano e enter ni user pasok parin dun sa condition
Naka loop na if else lang tapos, nilagyan ko nalang ng A,B,C,D yung mga name ng items para madali lang e if else. Then yung answer na variable is naka auto UPPERCASE para kahit ano e enter ni user pasok parin dun sa condition

can you help me po literal po kasi na hindi ko alam paano umpisahan.
Ano po coverage nito? Arrays and loops lng ba?
- Define a multidimensional 3X5 string array (prod, stock, price) and initialize with values based on stated example (products list)
- Run a loop to read all the contents of the array
- Define a loop to read user data and terminate upon user response (y/N)
- get user input
- Define an inner loop to search product from the array
- if the product is found, get price, compute total, deduct stocks (modify index 1)
- show Totals
- else, show product not found!
- ask the user if he/he want to try again
- if yes, continue,
- else, break

1. Set your array properly so that it can be retrieved easily.
2. Retrieve product list
3. Perform transaction
a. Setup while loop to get transaction
b. Another while loop to buy the items and compute subtotal and total
4. Display total
Code:
static String Products[][]={
{"Bags", "10", "25.45"},
{"Shoes", "20", "67.64"},
{"Skirt","10", "43.23"},
};
Code:
//get product size
int prods = Products.length; //System.out.print(prods);
//Show product list
System.out.printf("%-15s || %-8s", "Stocks", "Cost"); //Header
System.out.print("\n");
for(int i=0; i<prods; i++){
System.out.printf("%-15s || %-8s\n", Products[i][0] + " - " + Products[i][1] , Products[i][2]);
}
System.out.print("\n");3. Perform transaction
a. Setup while loop to get transaction
b. Another while loop to buy the items and compute subtotal and total
4. Display total
