Hello, I need help!!! Very new to programming.
I need a program that will display a menu with the letters C,E,F,L and X for exit and allow the user to select a letter from the menu. If the user selects X,print an appropriate message and end the program. If the user selects one of the other letters, display letter in a large block CCCCCCCCC
CCCCCCCCC
CC
CC
CC
CC
CCCCCCCCC
CCCCCCCCC and then display the menu again. The program should conatin at least 7 methods. The following is what I have so far, but I am stumped how to get the large block output to the user's choice. I am thankful for any help!
import java.util.Scanner;
public class Letters
{

public static void main(String[] args)
{
displayMenu();
displayMessage();
printBlockC('C',3,10);
printBlockC('C',3,3);
printBlockC('C',3,10);
}
public static void displayMenu()
{
char letter;
String input;
Scanner keyboard=new Scanner (System.in);
System.out.println("Please enter a letter:\n C, E, F, or L, \n"+
" Enter X to exit");
input=keyboard.nextLine();
letter=input.charAt(0);



while(input.equalsIgnoreCase("C,E,F,L,"))
{
System.out.println("Please enter a letter:\n C, E, F,or L, \n"+
" Enter X to exit");
input=keyboard.nextLine();
letter=input.charAt(0);

}


}

public static void displayMessage()
{
System.out.print("Thank you for playing!");
}
public static void printBlockC(char symbol, int rows,int columns)
{
int i;
int j;
for(i=1;i<=rows;i++)
{
for(j=1;j<=columns;j++)
{
System.out.print(symbol);
}
System.out.println();
}
}
public static void printBlockE(char symbol, int rows,int columns)
{
int i;
int j;
for(i=1;i<=rows;i++)
{
for(j=1;j<=columns;j++)
{
System.out.print(symbol);
}
System.out.println();
}
}
public static void printBlockF(char symbol, int rows,int columns)
{
int i;
int j;
for(i=1;i<=rows;i++)
{
for(j=1;j<=columns;j++)
{
System.out.print(symbol);
}
System.out.println();
}
}
public static void printBlockL(char symbol, int rows,int columns)
{
int i;
int j;
for(i=1;i<=rows;i++)
{
for(j=1;j<=columns;j++)
{
System.out.print(symbol);
}
System.out.println();
}
}
}
}
