Loop driving me loopy!!!!!

Any advise on what is wrong with my loop please?

public static void main (String[]arg){

double loan;
double wages;
final int THRESHOLD= 10000;
double netInc;
double newBal=0;
double totalLoan;
double deduction;


System.out.println("Enter total amount of student loan taken");
loan=UserInput.readDouble();

System.out.println("Enter anticipated income");
wages=UserInput.readDouble();

newBal=loan*0.03;

netInc=wages-THRESHOLD;
deduction=netInc*0.09;

totalLoan=loan+newBal;

newBal=totalLoan-deduction;




System.out.println("Loan taken out: "+loan+" anticipated income "+wages);
System.out.println("Total plus interest: "+totalLoan);
System.out.println("Amount Re-paid: "+ deduction);
System.out.println("New balance: "+newBal);


}
public static calculate(double amount)
{


while(newBal >0.0){


newBal=loan*0.03;

netInc=wages-THRESHOLD;
deduction=netInc*0.09;

totalLoan=loan+newBal;

newBal=totalLoan-deduction;

System.out.println("Loan taken out: "+loan+" anticipated income "+wages);
System.out.println("Total plus interest: "+totalLoan);
System.out.println("Amount Re-paid: "+ deduction);
System.out.println("New balance: "+newBal);
}

else {

System.out.println("end ");

}

}




}//end main

}//end class

Yeah. The white space, the indentation and the code tag

If your problem is that the loop is not running, it's because calculate() is not called anywhere within main.

Or did you leave out some code?

and oh,

Code:

---

public static calculate()

---

is not a proper function signature

you need to add a return type
