Incompatible types error

[Joniela Geldenhuys]

Helo I've been struggling for hours now!! I'm doing a java course and I must code an interactive balancing calculator! my textbook does not explain the work very nice so now I'm stuck!!!
This is what I coded but when I compile they give me 4 errors saying incompatible types! I don't know what I'm doing and I feel so stupid!! Please help!!

import java.io.*;

public class Balance
{
	public static void main(String[] args) throws IOException
	{
		//Declare and construct variables
		float totalDeposits, totalChecks, totalFees;
		double beginnigBalance, endingBalance;
		String inputTotalDeposits, inputTotalChecks, inputTotalFees, inputBeginnigBalance;
		BufferedReader dataIn = new BufferedReader(new InputStreamReader(System.in));

		//print prompt and get input
		System.out.println("BALANCING YOUR CHECKBOOK");
		System.out.println();
		System.out.print("What is the balance from your last statement?  ");
			endingBalance = dataIn.readLine();
		System.out.print("What is the total amount of all deposits?  ");
			totalDeposits = dataIn.readLine();
		System.out.print("What is the total amount of all checks?  ");
			totalChecks = dataIn.readLine();
		System.out.print("What is the total amount of all transaction fees?  ");
			totalFees = dataIn.readLine();

		//Conversions
		totalDeposits = Float.parseFloat(inputTotalDeposits);
		totalChecks = Float.parseFloat(inputTotalChecks);
		totalFees = Float.parseFloat(inputTotalFees);
		beginnigBalance = Double.parseDouble(inputBeginnigBalance);

	 	//Calculations
	 	endingBalance = ((beginnigBalance + totalDeposits) - (totalChecks + totalFees));

	 	//Output
	 	System.out.print("Your new balance is $");
	 	System.out.println(endingBalance);
	}
}

Which book are you using, and how old is it?
Why are you using Readers, rather than a Scanner? A Scanner will give the input directly converted to the Java™ type required. Rather than your reading the line as a String and trying to assign that to the openingBalance amount, which is a double, so the compiler cannot achieve that (hence your error message), you can get the input converted directly without having to mess about with parseXXX method. So you can get the input in the correct type for money, which is not float nor double, but BigDecimal

import java.math.BigDecimal;
import java.util.Scanner;
 . . .
Scanner inScan = new Scanner(System.in);
 . . .
BigDecimal openingBalance = inScan.nextBigDecimal;
 . . .
BigDecimal deposits = inScan.nextBigDecimal;
 . . .
BigDecimal finalBalance = openingBalance.add(deposits).subtract(charges).subtract(chequesOut);
 . . .
System.out.printf("Final balance = £%.2f%n", finalBalance);

And there is a serious error in that code. So as not to let people think you are getting that code without any effort, I shall "forget" to correct that error (which appears twice). And I have respelt some of your variable names.
