The formal parameters of a method can be seen only by the statements of their own method. This means that if a method tries to use a parameter of some other method, the compiler will find a syntax error.
Here is the
CheckingAccount class again,
this time with a new definition of the
toString() method
class CheckingAccount
{
. . . .
private int balance;
. . . .
public void processDeposit( int amount )
{
return "Account: " + accountNumber + "\tName: " + accountHolder +
"\tBalance: " + amount + "\tUse Count: " + useCount;
}
// modified toString() method
public String toString()
{
System.out.println( balance + "\t" + amount );
}
}
Is this toString() method correct?
