telephone word generator

[rufus1277]

Hi everybody, very new to this forum and I very much like what I see. I have a coding assignment due very soon and it is very very rough. It is basically a telephone word generator, where I ask the user to enter a seven digit telephone number (sans 0 and 1) and then the program generates all possible letter combinations. I then have to use a printstream object to write to a file all the possible word combinations. It works, but can you help me clean it up. This is what I have so far:


import java.util.Scanner;

public class NumberToWord {

public static void main(String[] args)

{

char number2[] = { 'A', 'B', 'C' };
char number3[] = { 'D', 'E', 'F' };
char number4[] = { 'G', 'H', 'I' };
char number5[] = { 'J', 'K', 'L' };
char number6[] = { 'M', 'N', 'O' };
char number7[] = { 'P', 'R', 'S' };
char number8[] = { 'T', 'U', 'V' };
char number9[] = { 'W', 'X', 'Y' };

char Letter0[] = { ' ',' ',' ' };
char Letter1[] = { ' ',' ',' ' };
char Letter2[] = { ' ',' ',' ' };
char Letter3[] = { ' ',' ',' ' };
char Letter4[] = { ' ',' ',' ' };
char Letter5[] = { ' ',' ',' ' };
char Letter6[] = { ' ',' ',' ' };
char Letter7[] = { ' ',' ',' ' };

Scanner scanner = new Scanner( System.in );
Character phoneArray[] = new Character[ 7 ];

System.out.print( "Please enter a phone # " );
String phoneNumber = scanner.nextLine();

//Convert phoneNumber string to array of characters
for( int i=0; i < phoneNumber.length(); i++ ) {
phoneArray[i]=(new Character(phoneNumber.charAt(i)));
}

for (int i=0;i < phoneArray.length; i++) {
if ( phoneArray[i].equals('0') ){
System.out.println("Invalid Input (0)");
System.exit(1);
}
else if ( phoneArray[i].equals('1') ){
System.out.println("Invalid Input (1)");
System.exit(1);
}

}

Please be more specific what you mean by "clean it up". Also, try and format any code using the CODE tag in your post- it makes it a lot easier to read.
