Looping through all main() arguments

Question

• The application will request a series of input words/string using the main arguments.
  
• It will determine if per input string entered ends in a consonant, a vowel, an odd number, an even number, or a special symbol.
  
• It should also be able to count the number of characters per word input.

So far, this is what I have:

public static void main(String[] args) {
    if(args.length > 0) {
        String regExVowels = ".*[AEIOUaeiou]$";
        // regEx Strings

        char[] caMainArg = null;
        String strMainArg = null;

        for(String arg: args) {
            // Convert each String arg to char array
            caMainArg = arg.toCharArray();

            // Convert each char array to String
            strMainArg = new String(caMainArg);
        }

        System.out.print(strMainArg + " - " + strMainArg.length());

        // if-else conditions

    } else {
        System.out.println("No arguments passed!");
    }
}

It works, but it only takes the last argument. For example:

Eclipse > Run Configurations... > Arguments

kate middleton sep30 jan25 `

It will only output:

` - 1 - special character

My desired output is:

kate - 4 - vowel
middleton - 9 - consonant
sep30 - even number
jan25 - odd number
` - 1 - special character

I am unsure as to how to loop through the arguments and print the appropriate results.

Solution 1

You close your for loop too early.

You do:

   for(String arg: args) {
        // Convert each String arg to char array
        caMainArg = arg.toCharArray();

        // Convert each char array to String
        strMainArg = new String(caMainArg);
    }
    System.out.print(strMainArg + " - " + strMainArg.length());

    if(regExVowels.matches(strMainArg)) {
        System.out.print(" - vowel");

    } else if(regExUpperConsonants.matches(strMainArg) ||

    .....

You need to do :

   for(String arg: args) {
        // Convert each String arg to char array
        caMainArg = arg.toCharArray();

        // Convert each char array to String
        strMainArg = new String(caMainArg);
        System.out.print(strMainArg + " - " + strMainArg.length());

        if(regExVowels.matches(strMainArg)) {
            System.out.print(" - vowel");

        } else if(regExUpperConsonants.matches(strMainArg) ||

        ....

    }

Solution 2

Put,

    System.out.print(strMainArg + " - " + strMainArg.length());

    if(regExVowels.matches(strMainArg)) {
        System.out.print(" - vowel");

    } else if(regExUpperConsonants.matches(strMainArg) ||
            regExLowerConsonants.matches(strMainArg)) {
        System.out.print(" - consonant");

    } else if(regExEven.matches(strMainArg))    {
        System.out.print(" - even number");

    } else if(regExOdd.matches(strMainArg)) {
        System.out.print(" - odd number");

    } else {
        System.out.print(" - special character");
    }

Inside your loop towards the bottom that you already have that does loop through the arguments, your "for(String arg: args) {" line about 10 lines down.

Thank you, I believe the last }else{ must not be included.
