    Default an idea for a method

    Im not sure that im posting in the the right place.
    I writing a code that should recieve a string ("HELLO"), make it upper case, then print the whole string as huge as:
    A =
    a
    a a
    aaaaa
    a a
    a a
    I think only of the way of comparing by Switch each letter (such as 'Z' is 90), as long as i do a "for loop" and check by string[0] to string [max], or by "char array".
    I tried so many times and used many ways but nothing seems promising yet. Please give me an idea for finish it.

    This is my last try for only letters A and B, hope you will understand.

    	public static void main(String[] args) {
    		Scanner input = new Scanner(System.in);
    		char x[] = input.nextLine().toCharArray();
    		String a1, a2, a3, a4, a5, b1, b2, b3, b4, b5, c1, c2, c3, c4, c5, d1, d2, d3, d4, d5;
     
    	word1(x[0]);//first letter
    	word2(x[1]);
    	word3(x[2]);
    	word4(x[3]);
    	System.out.println(new String(a1)+new String(b1)+new String(c1)+new String(d1));
    	System.out.println(new String(a2)+new String(b2)+new String(c2)+new String(d2));
    	System.out.println(new String(a3)+new String(b3)+new String(c3)+new String(d3));
    	System.out.println(new String(a4)+new String(b4)+new String(c4)+new String(d4));
    	System.out.println(new String(a5)+new String(b5)+new String(c5)+new String(d5));
    	}
     
     
    private static void word1(char c){//bring first letter!
    	String a1, a2, a3, a4, a5;
    	switch (c) {
    	case 90:
    		a1 = "    a    ";
    		a2 = "   a a   ";
    		a3 = "  aaaaa  ";
    		a4 = " a     a ";
    		a5 = " a     a ";
    		break;
    	case 71:
    		a1 = "bbb  ";
    		a2 = "b  b ";
    		a3 = "bbb  ";
    		a4 = "b  b ";
    		a5 = "bbb  ";
    		break;
    	}
    }
    private static void word2(char c){//bring first letter!

    I don't know of any way to get a String with letters in the shape of a letter than the one you chose. One simplification might be to put the Strings into an array instead of having 5 separate Strings:
           String[] letterA = {"    a    ",
                         		"   a a   ",
                         		"  aaaaa  ",
                         		" a     a ",
                                    " a     a "};
            for(String line : letterA) {   //  Print the lines in a letter
               System.out.println(line);  
            }
    If you don't understand my answer, don't ignore it, ask a question.

                         		"   a a   ",
                         		"  aaaaa  ",
                         		" a     a ",
                                    " a     a "};
            for(String line : letterA) {   //  Print the lines in a letter
               System.out.println(line);  
            }
    I will do a "switch" loop with all the letters by cases.
    The problem is that each letter has 5 lines, and Im printing from left to right - so i can write like this (in big letters):
    H
    E
    L
    L
    O
    If I would wanted to do this then I'd finish it already.
    I changed the code and maybe now it will be more clear:
    package sos;
    import java.util.Scanner;
     
    public class brb {
     
    	public static void main(String[] args) {
    		Scanner input = new Scanner(System.in);
    		String d=""; //for method's return
    		System.out.println("enter a string: ");
    		String x = input.nextLine();
    		String line1="", line2="", line3="", line4="", line5="";
    		char y;
     
    		for (int i=0; i<=x.length(); i++) {
    			y = x.charAt(i);
    			word(y);
    			line1=line1+d.substring(0,7);
    			line2=line2.concat(d.substring(8,15));
    			line3=line3.concat(d.substring(16,23));
    			line4=line4.concat(d.substring(24,31));
    			line5=line5.concat(d.substring(32,39));
     
    			//take 8 chars from 'd' and put them in 'line1-5'
    		}
     
     
    	System.out.println(line1);
    	System.out.println(line2);
    	System.out.println(line3);
    	System.out.println(line4);
    	System.out.println(line5); //print out the full string
    	}
     
     
    private static String word(char y){//bring first letter!
    	String d="";
    	switch (y) {
    	case 41:
    		d=d.concat( "   a    "); // sum of 8 chars
    		d=d.concat( "  a a   ");
    		d=d.concat( " aaaaa  ");
    		d=d.concat( "a     a ");
    		d=d.concat( "a     a ");
    		break;
    	case 42:
    		d=d.concat( "bbb     ");
    		d=d.concat( "b  b    ");
    		d=d.concat( "bbb     ");
    		d=d.concat( "b  b    ");
    		d=d.concat( "bbb     ");
    		break;
     
    		/*cases 43-90 for 'C'-'Z' (inside 'word' method)
    		 * 
    		 * 
    		 */
     
    	}
    	return d;
    }
     
     
    }
     
     
    /*
    import java.util.Scanner;
     
    Scanner input = new Scanner(System.in);
    char word[] = input.nextLine().toUpperCase().toCharArray(); //CAPITAL LETTERS!
    int max = word.length-1;
    char x[] = input.nextLine().toCharArray();
    */

    Im pretty sure I did a tone of mistakes with "char" and "String", but that shows my problem as combining lines of each letter with the previous one.
    Thanks!

    Do you have further questions about your program?

    Note: The case statements can be code using the char, they do not have to be coded as ints:
       case 'a':
       case 'A':

    Yes, Im asking for an idea of how doing that.
    A friend told me earlier about an "image" you can create and put each "big letter" in that image then print them all in the same line?
    case statements - noted.

    how doing that.
    Sorry I don't understand what it is you are trying to do. What is the "that"?
    My suggestion was to put each letter into an array of lines and then print the contents of the arrays one line at a time.
    If you don't understand my answer, don't ignore it, ask a question.
