Converting the case of a string

Is there a way to convert the case of a string?I have a class called Word that holds a string and an integer. The Word type is being placed into a Binary Search Tree and then I need to change the case of the string portion.hughveal

Did you read the String API?

toUpperCase()toLowerCase()

And assign the dukes you promised in the last thread to paul and that other dude.

I have seen that the toLowerCase exists, but I need to make a method for this Word class in order to use it. I tried putting the characters of the string portion in a character array, but I kept getting a dereferencing error.

Dukes have been assigned. Sorry it took so long, I am new here.

I don't understand what you did other than somewhere I guess you tried to call toLowerCase or some other method on a char probably.

Post your code.

So your problem isn't really "Is there a way to convert the case of a string?", but rather, you have a bug in your code.

You'll get better responses if you're more forthcoming with the real issues.

That includes posting the actual error message you're getting, and the actual code that's causing it.

It was a few changes ago. I will recode it and post it for everyone to see.

Then you question isn't about converting the case of a String, Its about how to write code!

If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)",

see http://homepage1.nifty.com/algafield/sscce.html,

that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.

Don't forget to use the "Code Formatting Tags",

see http://forum.java.sun.com/help.jspa?sec=formatting,

so the posted code retains its original formatting.

Gee, I'm slow at the reply...

I don't want it to seem as if I was trying to hide something. The reason I didn't post the code was because I was sure if my logic was sound, and should be trying it the way I decided to go by using a character array. As soon as I recode the toLowerCase method, I will post.

Also in cases like this, when you have to do things because an assignment requires you to, but these things would normally be considered awkward or extraneous (e.g., duplicating existing APIs) you should probably just announce it as such, and even quote the homework assignment in the question.

Otherwise, as you've seen, people will do the reasonable thing and point you to the API, which normally is the correct thing to do but in this scenario just wastes their time and yours.

Here is the code for the Word class I created:

public class Word

{

private String Phrase;

private int counter;

//Empty Constructor

public Word()

{

Phrase = null;

counter = 0;

}

//constructor with 2 arguments

public Word(String phr, int cnt)

{

Phrase = phr;

counter = cnt;

}

//Constructor with one argument

public Word(String phr)

{

Phrase = phr;

counter = 0;

}

//equals() method

public boolean equals(Word looking)

{

boolean status;

if(Phrase.equals(looking.Phrase)&& (counter != looking.counter))

status = true;

else

status = false;

return status;

}

//toLowerCase

public String toLowerCase(String shifter)

{

char ch;

int lng;

lng = shifter.length();

for(int i = 0; i < lng; i++)

{

ch = shifter.charAt(i);

ch = shifter.toLowerCase(ch);

}

//compareTo method

//toString method

public String toString()

{

String describer = Phrase + ", " + counter;

return describer;

}

//setPhrase

public void setPhrase(String p)

{

Phrase = p;

}

//setCount

public void setCount(int c)

{

counter = c;

}

//getword

public String getWord()

{

return Phrase;

}

//getcount

public int getCount()

{

return counter;

}

The error I get is:

Word.java:50: cannot find symbol

symbol : method toLowerCase(char)

location: class java.lang.String

ch = shifter.toLowerCase(ch);

You're calling String.toLowerCase(charVariable)

if you look at String, you'll see that it doesn't have a call of this method that takes a character argument and returns a char.

Have a look at Character:

Thanks for all of the ridicule, and little help. After the barrage of insults I figured it out. Thanks to those that helped.
