 public class JavaCharacterisAlphabeticExample2 { public static void main(String[] args) { // Initialize the codepoints int codepoint1 = 87; int codepoint2 = 49; int codepoint3 = 63; // Check if the first codepoint is alphabet or not. boolean checkAlp1 = Character.isAlphabetic(codepoint1); if(checkAlp1){ System.err.print('Codepoint ''+codepoint1+'' is an alphabet.
'); } else{ System.out.print('Codepoint ''+codepoint1+'' is not an alphabet.

'); } else{ System.out.print('Codepoint ''+codepoint2+'' is not an alphabet.
'); } // Check if the third codepoint is alphabet or not. boolean checkAlp3 = Character.isAlphabetic(codepoint3); if(checkAlp3){ System.err.print('Codepoint ''+codepoint3+'' is an alphabet.
'); } else{ System.out.print('Codepoint ''+codepoint3+'' is not an alphabet.
