letters are in ascending order or not in ascending order.

[hawkesey]

Hello

I am currently learning about OO programming with java i am starting to get the grasp of it to some extent and i am finding it enjoyable.

One of the exercises i have been set by my lecturer, here is the brief:-

Read in a word and display if the letters are in ascending order or not in ascending order. Ignore letter case in your comparison.

I have an idea how to achieve this it is just implementing it that im not sure about.

Any help would be appreciated

Thanks

Josh

What have you tried? Where are you stuck? Which part of this is giving you trouble?

Well i have had the thought that i need to get the program to look at each letter in the string and compare it to the lasst to see see if it is >= to the last. and if this is true for all of the letters then it will return true and false if not. Here is what i have done so far it is just my thoughts really i have not yet come across away to implement how i think the problem should be solved.

public class Main
{
public static void main (String args[])

{

System.out.print("#Enter phrase\n");
String P=BIO.getString();


while (! P.equals("END"))
{
/**
if (R.equals("TRUE"))
{
System.out.printf("%s letters in ascending order\n",P);
}

else if (R.equals("FALSE"))
{
System.out.printf("%s letters not in ascending order\n",P);
}
**/

System.out.print("#Enter phrase\n");
P=BIO.getString();

for (int x=0; x<P.length; x=x+1)
{
}
}
}
}



Thanks

also is there an area of this site where i can upload code and get some feedback on it.

Yep, that would be the best way. The String class has a method to extract a single letter. It also has methods to change the case (upper-lower, lower-upper) to handle the ignore case requirement.

i have this so far it is an adaptation to a program that i wrote to count vowels in a phrase.

public class Main
 {   
    public static void main (String args[])
        
     {  
           String R="a";
          
           System.out.print("#Enter phrase\n");
           String P=BIO.getString();
           
            
           while (! P.equals("END"))
            {
               
               if (R.equals("TRUE"))
                {
                   System.out.printf("%s letters in ascending order\n",P);
                }
                    
               else if (R.equals("FALSE"))
                {
                   System.out.printf("%s letters not in ascending order\n",P);
                } 
                
               System.out.print("#Enter phrase\n");
               P=BIO.getString(); 
            
               for (int x=0; x<P.length(); x=x+1) 
                  {
                     if (P.charAt(x)>=x)
                      { 
                         R="TRUE";
                      }  
                     else if (P.charAt(x)<x)
                      {
                          R="FALSE";
                       }   
                  } 
            }
    }
  }

i have this so far

Good for you. Do you have a question? I have one. Why are you using "TRUE" and "FALSE" as Strings instead of booleans?

Can i just say that there is absolutely no need for rudeness. As i said i am not that competent with java yet.

I don't see any rudeness there, just a word of encouragement and two questions you need to answer to get better help here.

it just appeared to be written in a way that sounds rude. sorry if there is a misunderstanding
