Question

Hi. I already have a java program made that prompts the user to enter a file name. After doing this, my program already knows how to read the file that the user enters. The file that the user enters is file that contains different people names.

I know how to alphabetize a string, but my problem is I do not know how to alphabetize something from a file.

In other words, if I am given that I have to sort three letters, I can do that:
String[] strArray = new String[] {"z", "a", "C"};
Arrays.sort(strArray);

BUT I do not know how to sort something like this:
String[] names = new String[20]

This is my thinking on how to solve this issue, but I'm not sure if I am correct:

so i have in my main:
String[] names = new String[20]
ascendingSort(names, names.length);

now i am going to create another method:
public static void ascendingSort(String[] names, double length)

?
Please help, I'll rate

Explanation / Answer

Dear,

Here is the method definition for your post...

public static void ascendingSort(String[] names, double length) {

        String temp;//to store temporary data

        //outer loop

        for (int i = 0; i < length - 1; i++) {

            //inner loop

            for (int j = 0; j < length - 1; j++) {

                //comparing adjacent strings

            if (names[j].compareToIgnoreCase(names[j + 1]) > 0)

                {

                    //if condition satisfies swap two strings

                    temp = names[j];

                    names[j] = names[j + 1];

                    names[j + 1] = temp;

                }

            }//end of inner loop

        }//end of outer loop

    }//end of method

Hope this helps you....
