I think my Math calculation is correct now. I just need help if anyone could with getting it into separate methods. I do not know why I am updating this since no one seems to want to help me anyhow. I just holding out hope.

I recommend reading the following, and take careful note of where semicolons need to be placed.
The while and do-while Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)

 
 
	import java.util.Scanner; // import scanner
 
	public class Loan {
 
	static Scanner input = new Scanner(System.in); // create scanner object usable in all methods
 
 
 
		public static void main(String[] args) {
 
			// Declarations
			int cont = 1;
			double loanAmount = 1;
			double interest = 1.1;
			double numberYears = 1;	
			double monthlyInterest = interest/1200;
		    double monthlyRepayment;
		    double result = max(loanAmount, interest, numberYears);
		    //endDeclarations
 
			System.out.println("Welcome to the loan Calculator. I will help you calculate the monthly payments on a loan"); //welcome statement
 
			System.out.print("Would you like to calculate loan payments now? Please enter 1 for Yes anything else for No: "); //loop variable input
			cont = input.nextInt();
 
			while(cont == 1){ // begin while loop
				//begin collecting data for variables
				System.out.print("Please enter the loan amount in dollars and cents. Example: $1500.75:$ ");
				loanAmount = input.nextDouble();
 
				System.out.print("Please enter the interest rate. Example: 5.7%:% ");
				interest = input.nextDouble();
 
				System.out.print("Please enter the number of years the loan will be for. Example: 15:  ");
				numberYears = input.nextInt();
 
 
				System.out.println("The Monthly Payment: $" +(int) (result*100/100));
 
				System.out.println("Would you like to calculate another Loan? Please enter 1 for Yes: ");
				cont = input.nextInt();
 
		      }
 
				System.out.println("Thanks for using the Loan Calculator!");
		}
 
				public static double max(double loanAmount, double monthlyInterest, double numberYears ){
 
					double monthlyRepayment = loanAmount* monthlyInterest/(1-(Math.pow(1/ (1+monthlyInterest), numberYears*12)));
 
					return monthlyRepayment;
 
 
 
 
 
 
			}
	}

Now it really wont work
