Overloaded Constructor

lad12

Anyone tell me how to write an Overloaded constructor in a class in java?

Stark

It's the same as a normal constructor method except with different parameters.

Eg: default constructor: public Test() {...}

overloaded constructor: public Test(int a, int b) {...}

You obviously need at least 2 definitions for the method or else you're not overloading anything.

ok..

so for this question

An overloaded constructor for Current Account which takes an Account Number argument only, and uses a default balance of 0.0 and minimum balance of 100.0
would this do it...

class CurrentAccount extends BankAccount{
private double minimum;
class CurrentAccount(int acctNum, double bal){
Super(accNum, bal);
}

public int accNum(int accountNumber, int Balance){
Balance = 0.0
minimum = 100.0
}
}

Stark

No because the constructor is only supposed to "takes an Account Number argument only"
and a constructor begins with keyword public, not class

public CurrentAccount(int acctNum)

I don't know what your BankAccount class looks like so I can't comment on your constructor. And your int accNum method doesn't make sense, why would a getter be changing the values of things?

From the way this is phrased, I'm guessing that there's also a constructor that takes all three arguements, and then a constructor that takes one arg and uses the default values

public CurrentAccount(int accNum, double bal, double minBal)
{
    ...
}

public CurrentAccount(int accNum)
{
    this(accNum, 0, 100);  // use other contructor with these default values
}
