The problem is "Conversion = '-'". The source code is here, I had commented the "printf" to avoid some problems, always cased by "print": this is a program used for calculating Loan in year.
import java.util.*;
public class Loan{
public static void main(String args[]){
final double MIN = 0.05;
final double MAX = 0.08;
final double ADD = 0.125;
Scanner input = new Scanner(System.in);
System.out.print("Loan Amount: ");
double amount = input.nextDouble();
System.out.print("Number of Years :");
int years = input.nextInt();
/*
for(double r = MIN; r < MAX;r = r + ADD){
double R = Math.pow((1+r),years);
double monthlyPayment = r * R * amount / 12/(R-1);
double totalPayment = 12*monthlyPayment*years;
System.out.printf("%-20s%-20s%-20\n","InterestRate","MonthlyPayment","TotalPayment");
System.out.printf("%%-20f%-20.2f%-20.2f\n",r,monthlyPayment,totalPayment);
}
*/
}
}

You're missing a format specifier character, replace
System.out.printf("%-20s%-20s%-20", "InterestRate", ...)
with
System.out.printf("%-20s%-20s%-20s", "InterestRate", ...
^
I Guess you want this,
System.out.printf("%-20s%-20s%-20s", "InterestRate",
"MonthlyPayment", "TotalPayment\n");
System.out.printf("%-20.2f%-20.2f%-20.2f\n", r, monthlyPayment,
totalPayment);
Use below code it will work
System.out.printf("%-20s %-20s %20s %n","InterestRate","Monthly Payment","Total Payment\n");
System.out.printf("%-20f %-20.2f %-20.2f\n",r,monthlyPayment,totalPayment);
Let me know if anything else required
