In the following question, we are supposed to ask the user to enter a character and check if it is a vowel or consonant using if-else construct.

The standard algorithm will be:

Enter and Store the User Input.
Create a Duplicate of the user input and change its case for uniformity.
Use if-else construct to compare. Now there might be to sub-cases: Either it might be a vowel or might not be.
If it is a vowel, straightforwardly print a result of success.
If it is not a vowel, it either might be a consonant or a special characters.
Use ASCII Values of Alphabets to do the same.
Print result accordingly.

ASCII VALUES:\n

A-Z: 65 to 90.\na-z: 97 to 122.\n0-9: 48 to 57.

Source Code:

/* Program to check if entered character is vowel or consonant using if-else*/\nimport java.util.*;\nclass ConsVowel\n{\npublic static void main()\n{\nScanner inp=new Scanner(System.in);\nSystem.out.print(\"\\n Enter Character: \");\nchar c=((inp.nextLine()).charAt(0));\nchar z=Character.toUpperCase(c); //Changing Value to Upper Case for uniformity.
\nif(z=='A' || z=='E' || z=='I' || z=='O' || z=='U') //Checking if Vowel\nSystem.out.println(c+\" is a Vowel.\");\nelse\n{\nif((c>=65 && c<=90) || (c>=97 && c<=122) ) // Checking if character is special character.\nSystem.out.println(c+\" is a Consonant.\");\nelse\nSystem.out.println(c+\" is a Special Character.\");\n}
\n}\n}\n

Output:

Enter Character: X\nX is a Consonant.\nEnter Character: i\ni is a Vowel. \n

Enter Character: @\n@ is a Special Character.
