Do you want to convert ints to chars    int yourInt   33  char ch    char  yourInt  System out println yourInt   System out println ch      Output     33        Or do you want to convert ints to Strings   int yourInt   33  String str   String valueOf yourInt     Or what is it that you mean

There are many ways to convert an int to ASCII  depending on your needs  but here is a way to convert each integer byte to an ASCII character   private static String toASCII int value        int length   4      StringBuilder builder   new StringBuilder length       for  int i   length - 1  i  gt   0  i--            builder append  char    value  gt  gt   8   i    amp  0xFF              return builder toString        For example  the ASCII text for  TEST  can be represented as the byte array   byte   test   new byte      byte  0x54   byte  0x45   byte  0x53   byte  0x54      Then you could do the following   int value   ByteBuffer wrap test  getInt       1413829460 System out println toASCII value       outputs  TEST       so this essentially converts the 4 bytes in a 32-bit integer to 4 separate ASCII characters  one character per byte

In Java  you really want to use Integer toString to convert an integer to its corresponding String value  If you are dealing with just the digits 0-9  then you could use something like this   private static final char   DIGITS         0    1    2    3    4    5    6    7    8    9     private static char getDigit int digitValue       assertInRange digitValue  0  9      return DIGITS digitValue       Or  equivalently   private static int ASCII ZERO   0x30   private static char getDigit int digitValue      assertInRange digitValue  0  9     return   char   digitValue   ASCII ZERO

In fact in the last answer      String strAsciiTab   Character toString  char  iAsciiValue   the essential part is  char iAsciiValue which is doing the job  Character toString useless   Meaning the first answer was correct actually     char ch    char  yourInt   if in yourint 49  or 0x31   ch will be  1

If you first convert the int to a char  you will have your ascii code    For example       int iAsciiValue   9     Currently just the number 9  but we want Tab character        Put the tab character into a string     String strAsciiTab   Character toString  char  iAsciiValue
