Plz check whether my logic is correct or not??? question is check whether the number is fascinating number or not

Multiplying a number by two and three separately, the number obtained by writing the results obtained with the given number will be called a fascinating number. If the result obtained after concatenation contains all digits from 1 to 9, exactly once. Ex 192......... when 192*1+192*2+192*3=192384576 .. all no.s are occurring only once. https://code.sololearn.com/clJS0kcd7TVM/?ref=app

In your loop part logic not work. it only works for 1 iteration. in loop, take i as char (not int), from '1' to '9' and compare i==ch.charAt(j) , if yes increment a count. No need of else part. If count==9 then print fascinate else not. Before this , remove duplicates from final String.. In your program, a.toString(a) is wrong , it should be Integer.toString(a); Your else part have return 1 and if part have break statement so it only work for 1 iteration.. Try again and check it with main method.. For any other, . . post a reply... Hope it helps..

I think your logic is correct but the program is not proper. There is no main method and it looks like incompleted. Here check this https://code.sololearn.com/cf2Bpjh3h5bO/?ref=app I'm not very much familiar with java built-in methods so it'll be more numeric.
