You didn't show much effort here, but String#replaceAll is well-suited to this problem. We can try removing classes of characters which don't match what we want to target.

String input = "abc12$%";
System.out.println("alphabet: " + input.replaceAll("(?i)[^A-Z]+", ""));
System.out.println("numeric: " + input.replaceAll("[^0-9]+", ""));
System.out.println("symbol: " + input.replaceAll("(?i)[A-Z0-9]+", ""));

This prints:

alphabet: abc
numeric: 12
symbol: $%

Here is an explanation of the regex patterns used above. Note that we replace with empty string in all cases, so we are matching what we want to remove.

(?i)[^A-Z]+    match any non letter, case insensitive (?i)
[^0-9]+        match any non digit
(?i)[A-Z0-9]+  match any alphanumeric character (i.e. a letter or number)

This is a logical question, so I prefer only to give idea instead of exact solution.

Try this:

read the ASCII value of each character in string, analyze which character falls in which range of ASCII values, add each character in 3 different array each for alphabet, number and special character, and finally print all the array in string.
