howd you draw class digarams

[ayazyounis]

for example from the follwing code,:

import javax.swing.*;

public class PriceOfCoffee {

public static void main(String[] args) {

int numberOfUnits, unitWeight;
final double pricePerPound=5.99;
double totalPrice, totalPriceWithTax;
final double salesTax=0.0725;

String inputStr;

inputStr = JOptionPane.showInputDialog(null, "Number of bags sold: ");
numberOfUnits = Integer.parseInt(inputStr);

inputStr = JOptionPane.showInputDialog(null, "Weight per bag: ");
unitWeight = Integer.parseInt(inputStr);
// computation
totalPrice = unitWeight * numberOfUnits * pricePerPound;
totalPriceWithTax = totalPrice + totalPrice * salesTax;

System.out.println("Number of bags sold: " + numberOfUnits);
System.out.println(" Weight per Bag: " + unitWeight + "lb");
System.out.println(" Price per pound: $" + pricePerPound);
System.out.println(" Sales tax: 7.25%");
System.out.println(""); // miss a line
System.out.println(" Total price: $" + totalPriceWithTax);

}
}

varies according to the university or boss who is asking

i would draw a big square box
in the top left corner i would list the member variables, using italics for private/protected ones

then i would draw a sequence of rectangles sticking out of the right hand side of the box, with the method names, public-ness and expected arguments in them. see the attachment

this might not be how your uni expects. CHECK.

also, final variables should BE_WRITTEN_LIKE_THIS, k?

You can use a program like Visio to draw diagrams like relational or flow charts.
