My program is not case sensitive it does not display the output my proff wants PLEASE HELP! I don't know how to make it case sensitive


The output should be:
As entered
0:a:apple
1:a:Apple
2:z:Zone
3:a:apple
Bubble Sorted
0:a:apple
1:a:Apple
3:a:apple
2:z:Zone
Selection Sorted
1:a:Apple
0:a:apple
3:a:apple
2:z:Zone

My program does:
As entered
0:a:apple
1:a:Apple
2:z:Zone
3:a:apple
Bubble Sorted
1:a:Apple
2:z:Zone
0:a:apple
3:a:apple
Selection Sorted
1:a:Apple
2:z:Zone
0:a:apple
3:a:apple

The output you've posted is hard to understand.
Can you show the ordering you would like for the characters: a A b B c C 1 2

I believe A a B b C c

But beats me the proff is confusing me also...

can you try editing my code to look like the output given?

To get that ordering you'll need to write your own compare() method.
The normal order for characters is: ABC...Zabc...z. All uppercase followed by the lowercase.

What material have you covered in your course that you can use to solve this problem?
I need to know to so I don't do something that you haven't studied yet.

We have gone through everything i used in my coding lol... just try it and i'll see if its way too complicated please & thanks

Ok. We'll try to write a compare method with you. First write one to replace the one that you are using now. Then change it to sort with the ordering that you want.

Write a method that takes two strings: S1 and S2 as input and returns an int: greater than 0 if S1 comes after S2, 0 if s1 == S2 and less than 0 if S1 comes before S2.
The method will take the Strings one char at a time in a loop from each string (Assume strings are the same length to begin with) and subtracts the char from S2 from the char
from S2. If the results don't equal 0 it returns the results. If equal 0 it goes to the next characters and tests again. If all are zero the method returns 0.
For testing: Write a very simple short program that passes two strings short same length strings to the method and prints out the results. Use this program to test all three cases.

Compare the characters one by one. As soon as a pair of characters being compared are not equal return the results of the compare.

if s1 comes after s2

s1 comes after s2 if its letters are greater in value than the letters of s2.

If you don't use the standard ASCII ordering for the letters, you will need a way to assign values to each letter so that the ones that come first are lower in value than the ones that come later.

Edited 6 Years Ago by NormR1: n/a

I wrote this but i don't know what to do from there

int method(String s1, String s2){
        int num = 0;
        int num1 = 0;
        for (int i = 0; i < s1.length(); i++){
             num += (int)s1.charAt(i);
        }
        
        for (int i = 0; i < s2.length(); i++){
             num1 += (int)s2.charAt(i);
        }
        if (num > num1){
            return 2;
            
        }    
        if (num == num1){
            return 0;
            
        }  
        
        if (num < num1){
            return -2;
        }
    }

}

Where do you define the sequence of characters?
Which one is to come first and which one last.
Your code uses the ASCII values. So there will be no difference in ordering for your sort vs any other class's sort.

How can you assign values for the letters so they compare in the order that you want?
