Writing an application class?

[Joe Grimp]

I have the Date and Transaction class and i need to test them so i have to write an application class. How do i go about doing this?

Here is the transaction class -

class Transaction {

private double amount;
private double newBalance;
private boolean type;
private Date d;

public void readTransaction() {
char c;
d = new Date();
d.readDate();

do 
{
System.out.print("Is this transaction a withdrawal or deposit? (W or D)");
c = uuInOut.ReadChar();
uuInOut.ReadLn();
 
if (c != 'W' && c != 'w' && c != 'D' && c != 'd')
System.out.println("Invalid entry. Try again.");
 
}while (c != 'W' && c != 'w' && c != 'D' && c != 'd');
 
if (c == 'W' || c =='w')
type = true;
else
type = false;
System.out.print("Enter amount: ");
amount = uuInOut.ReadDouble();
}

public void printTransaction() {
 
d.printDate(); 
System.out.print("\t" +amount); 
 
if(newBalance < 0) 
{ 
System.out.print(-newBalance +"OD"); 
}
 
System.out.println("\t" +type); 
 
}
 

public boolean getType() {
return type;
}

public double getAmount() {
return amount;
}

public void setBalance(double value) {
newBalance = value;
}
}

You can use JUnit, as a Java programmer you will want to use TestCases to test your code.
