How convert number to letter in java?

Question

hi all ,

i have to convert number to letter like this :

if get 25 >> print Twenty five

can any one help me ?:

Answer 1

a very quick and efficient way would be to store the number's names in an array sequentially :

example : String numbers [] = new String[100];

numbers[0] ="zero";

....

However, the correct way would be to use a programmatic approach  :

NOTE : this is correct for numbers between 0 and 99 inclusive  ONLY ; however; u can expand the algorithm after u understand it if u need to go beyond 99

String smallNumbers[] = new String[10];

Now fill it up with the numbers from 0 to 20 manually :

smallNumbers[0] ="zero";

smallNumbers[1] ="one";

smallNumbers[2] ="two";

...

smallNumbers[9] ="nine";

Now for 11-19 , do it manually :

String mediumNumbers[] = new String[10];

mediumNumbers[0] ="ten";

mediumNumbers[1] ="eleven";

.....

mediumNumbers[9] ="nineteen";

Now   manually fill those slots in the array  who are dividable by 10 :

String  []  tenMultiples = new String[10];

tenMultiples[0] ="ten";

tenMultiples[1] ="twenty";

tenMultiples[2] ="thirty;

...

tenMultiples[8] ="ninety";

Now the logic :

assume the number is :

int x = 30 ;

Use this :

if( x >= 100 ) print "This method is only for numbers between 0 and 99 " ;

else if ( x >=0 && x <= 9 )      

              print     smallNumbers[x] ;

else if ( x >=10 && x <= 19 ) // if the number is  between 10 and 19 inclusive

{      

  int  y = x % 10 ;

  print  mediumNumbers[ y ] ;

}

else if ( x%10 == 0   ) // if the number is a multiple of 10

{      

  int  y = x % 10 ;

  print  tenMultiples[y -1];

}

else //any other number between 0 and 99 besides those mentioned above

{

  int smallPart = x % 10 ;

  int tensPart = x /10 ;

  

print "The number is "  tenMultiples [ tensPart-1 ]+ "-" +  smallNumbers[ smallPart ];

}

Test the code in the  programming language u r using ( u ain't mentioned it )...i did it in java ; change it into the language ur using ...

Good luck

Answer 3

you COULD put the words in an array. like var name['0','1','2','3','4'] ect.

then call the variable with your number name[0] = '0'
