public class StringCalculator {

static final String WORD = “346789ABCDEFGHJKLMNPQRSTUWXY”;
static final int lengOfSubString = 4;
* @param args
public static void main(String[] args) {

char[] wordArray = WORD.toCharArray();
int lengthOfWord = WORD.length();
System.out.println(“Length of the word : “+lengthOfWord);
String subString = “”;

Set<String> set = new HashSet<String>();
for(int a=0;a<lengthOfWord;a++){
for(int b=0;b<lengthOfWord;b++){
for(int c=0;c<lengthOfWord;c++){
for(int d=0;d<lengthOfWord;d++){
subString = “8”+wordArray[a] + wordArray[b] +wordArray[c]+wordArray[d];
