Java Programming

I'm a beginner to Java and I need to know how to do the following:

Write a program that will ask the user to enter the amount of a purchase. The program should then compute the state and county sales tax. Assume the state sales tax is 4 percent and the county sales tax is 2 percent. The program should display the amount of the purchase, the state sales tax, the county sales tax, the total sales tax, and the total of the sale (which is the sum of the amount of purchase plus the total sales tax). Hint: Use the value 0.02 to represent 2 percent, and 0.04 to represent 4 percent.

Can anybody help me?

  1. Post either pseudocode, or actual coding, in whatever shape they are in.

    If you do not know how to do either one of the two, post what you have learned, the name of your textbook, the chapters covered, and the course outline.

  2. // Create a Scanner object to read input.
    Scanner keyboard = new Scanner(System.in);

    // Get the Purchase Amount
    System.out.print(" What is the Purchase Amount?");
    purchaseAmount=keyboard.nextDouble( );

    stateSalesTax=0.04*purchaseAmount;
    countySalesTax=0.02*purchaseAmount;
    totalSalesTax=stateSalesTax+countySalesTax;
    totalSale=totalSalesTax+purchaseAmount;

    System.out.println( " Purchase " + purchaseAmount);
    System.out.println( " State Tax " + stateSalesTax);
    System.out.println( " County Tax " + countySalesTax );
    System.out.println( " Total Tax " + totalSalesTax +"\n_________");
    System.out.println( " Total Sale " + totalSale);

    }
    }
