This code primarily performs formatted printing in Java using the System.out.printf
method. Here's a detailed explanation of what this code does:
-
Creation of a Calendar Object:
Calendar cal = Calendar.getInstance();
- A
Calendar
object is created and initialized to the current date and time.
- A
-
Printing the Header with Date and Time:
System.out.printf(“Hitesh R. Pulimi- %tc\n”, cal);
- It prints the name "Hitesh R. Pulimi-" followed by the current date and time in a formatted manner (
%tc
). The%tc
format specifier prints the complete date and time formatted for the default locale.
- It prints the name "Hitesh R. Pulimi-" followed by the current date and time in a formatted manner (
-
Printing Quoted Text:
System.out.printf(“\”Receipt\” lab”);
- This prints the string
"Receipt" lab
. The\”
is an escape sequence to include quotation marks inside a string.
- This prints the string
-
Printing the Store Name:
System.out.printf(“\t\t Fish Store\n”);
- Prints "Fish Store" with two tabs (
\t\t
) at the beginning to align it towards the center. The\n
moves to the next line.
- Prints "Fish Store" with two tabs (
-
Printing a Header for Item and Amount:
System.out.printf(“Item\t\t\tAmount”);
- Prints "Item" and "Amount" with tabs (
\t
) for spacing between them to align the columns.
- Prints "Item" and "Amount" with tabs (
-
Printing Item Details:
System.out.printf(“%s\t\t$%6.2f\n”,”Red Fish”,84.99); System.out.printf(“%s\t\t$%6.2f\n”,”Yellow Fish”,5.91); System.out.printf(“%s\t\t$%6.2f\n\n”,”Green Fish”,4.99);
- Prints the item name (e.g., "Red Fish") and amount (e.g., $84.99) in a formatted way:
%s
is a placeholder for a string (e.g., the item name).%6.2f
is a placeholder for a floating-point value, formatted to 2 decimal places, and a total width of 6 characters including the decimal point.
- Each item's name is printed left-aligned, followed by the corresponding price.
- An extra
\n
moves the cursor to a new line for spacing after "Green Fish."
- Prints the item name (e.g., "Red Fish") and amount (e.g., $84.99) in a formatted way:
-
Calculating and Printing Subtotal:
System.out.printf(“%s\t\t$%6.2f\n”,”Subtotal”,84.99+5.91+4.99);
- Calculates the subtotal by adding the prices of the items (
84.99 + 5.91 + 4.99
) and prints it with the label "Subtotal".
- Calculates the subtotal by adding the prices of the items (
-
Printing Tax Amount:
System.out.printf(“%s\t\t$%6.2f\n”,”tax”,7.91);
- Prints the tax amount
$7.91
with the label "tax".
- Prints the tax amount
-
Calculating and Printing Total:
System.out.printf(“%s\t\t$%6.2f\n”,”Total”,84.99+5.91+4.99+7.91);
- Calculates the total by summing up the subtotal and tax (
84.99 + 5.91 + 4.99 + 7.91
) and prints it with the label "Total".
- Calculates the total by summing up the subtotal and tax (
Summary of Output:
The code produces a receipt-like formatted output, showing the following:
- A header with the user's name and the current date/time.
- The store's name ("Fish Store").
- A tabular list of items and their prices.
- Subtotal, tax, and the total amount due.
The output on the console would look something like this:
Hitesh R. Pulimi- Sat Oct 28 14:45:30 DST 2023
"Receipt" lab Fish Store
Item Amount
Red Fish $ 84.99
Yellow Fish $ 5.91
Green Fish $ 4.99
Subtotal $ 95.89
tax $ 7.91
Total $ 103.80
(Assuming the current date is Sat Oct 28 14:45:30 DST 2023
, and the amounts are as specified.)
