Thread: Applying Methods to Program

I'm just not quite getting the whole method thing. I get the general concept and even like, but applying it is another matter for me. Smaller programs, examples of simple method programs I get. But when it comes to 'methodizing' a larger program, I begin to have trouble. Case-in-point, below I'm attempting to add methods to a sequential program I wrote earlier. (The original is posted below the method-attempt.) If anyone cares to chime in, it would really be helpful to me.

import java.io.*;  
import java.util.*;  
import java.text.DecimalFormat;
 
 
 
 
public class Bank3 
{
	public static void main(String[] args) throws IOException
	{
 
		String firstLine; 
		String secondLine;
		String thirdLine;
		String fourthLine;
		String tempLine;  
		double fifthLine;
		double monthlyFee = 0;  
		double totalBalance = 0;  
 
 
 
 
 
		openRead();
		outPut();
 
	}	
 
 
 
		public static void openRead() throws IOException
		{
		File file = new File("AcctInfo.txt");   
		Scanner inputFile = new Scanner(file);    
		DecimalFormat formatter = new DecimalFormat("#0.00");  
 
		while (inputFile.hasNext()) 
			{
			String firstLine = inputFile.nextLine();
			while (!(firstLine.isEmpty()))  
				{
				String secondLine = inputFile.nextLine(); 
				String thirdLine = inputFile.nextLine();
				String fourthLine = inputFile.nextLine();;
				String tempLine = inputFile.nextLine();
				Double fifthLine = Double.parseDouble(tempLine);  
 
				double monthlyFee = 0;
				double totalBalance = 0;
 
 
 
				System.out.println("Account #:\t\t" + firstLine);
				System.out.println("Account Type:\t\t" + secondLine);
				System.out.println("Customer Name:\t\t" + thirdLine);
				System.out.println("Customer Type:\t\t" + fourthLine);
				System.out.println("Balance:\t\t$" + fifthLine);
 
 
				if (secondLine.equalsIgnoreCase("savings"))
					{
					monthlyFee = 0.00;
					}
				else if (fourthLine.equalsIgnoreCase("value") && fifthLine < 1500)
					{
					monthlyFee = 5.00;
					}
				else if (fourthLine.equalsIgnoreCase("value") && fifthLine >= 1500)
					{
					monthlyFee = 0.00;
					}
				else if (fourthLine.equalsIgnoreCase("advantage") && fifthLine < 1000)
					{
					monthlyFee = 10.00;
					}
				else if (fourthLine.equalsIgnoreCase("advantage") && fifthLine >= 1000)
					{
					monthlyFee = 0.00;
					}
				else if (fourthLine.equalsIgnoreCase("premier") && fifthLine < 25000)
					{
					monthlyFee = 30.00;
					}
				else if (fourthLine.equalsIgnoreCase("premier") && fifthLine >= 25000)
					{
					monthlyFee = 0.00;
 
					return monthlyFee;
					}
 
				}
 
				}}
				public static void outPut(double monthlyFee, fifthLine)throws IOException
				{
				System.out.println("Monthly Fee:\t\t$" + formatter.format(monthlyFee));  
				System.out.println("");  
				totalBalance += fifthLine;  
				firstLine = inputFile.nextLine(); 
				System.out.println("The total amount deposited: $" + formatter.format(totalBalance)); 
										inputFile.close();		
				}	
 
 
			}

Thanks for quick reply and link Zyrion. No particular questions about my code. I suppose I posted it to see if it elicited a "Hey, you have major logic errors" response. But I realize that it's a lot to look at, and such is not readily apparent. Anyway, step 3 in the summary you posted is actually a big reminder to me. May be one of the problems I'm having, i.e., not properly defining my methods. Thanks again Zyrion!
