Help on Beginners Program

Question

Hello, I need to write a program where the user can enter an amount borrowed, and interest rate and the number of yrs for mortage. Using TextReader.java i need to calculate the total amount to be reaid, then calculate the monthly payment based on 12 months per yr. and # of yrs of the mortage. My program shows to many errors... can someone please help me with my program?:
import java.text.*; // For Formatting Numbers
public class asst8
public static void main(String args[])
TextReader tr = new TextReader
amount = amount * Math.pow(1=rate/12);;
int monthly = "amount" / 12;
String amountDouble = tr.readDouble();
amount = (amountString);
System.out.println("Please enter amount borrowed:_");
System.out.println("Please enter interest rate:_");
System.out.println("Please enter number of years:_");
System.exit(o);

Answer 1

well, you define "amount" using "rate", before "rate" has been defined. same with "monthly".
it should prob say TextReader tr = new TextReader() instead of TextReader tr = new TextReader
tr is only used to aquire one value, it seems you are asking for three.
System.out.println("Please enter amount borrowed:_");
System.out.println("Please enter interest rate:_");
System.out.println("Please enter number of years:_");these questions should prob be asked before you try to read info from the user. like
System.out.println("Please enter amount borrowed:_");
Double amount=tr.readDouble();
System.out.println("Please enter interest rate:_");
Double rate=tr.readDouble();
System.out.println("Please enter number of years:_");
Double years=tr.readDouble();now do all your math with the values you received and then display
output. you really need to pay attention to the order in which things
happen. and read you error messages.
