reversing characters in a word

[hello12]

Hello,
I am new to java and i was having a hard time figuring out on how to do certain string manipulations. I was asked to read in a text file and reverse the words. So far, I have put all the words in the text file into an arraylist.
For example...
Hello World. ---> must be printed out as --> olleH .dlroW
right now when i print my arraylist i am getting
[ Hello, World.] I was thinking of somehow accessing each word from here and reversing it. But i am stuck at this point. ANy help would
be appreciated.
thanks

From there.. You can do it in many ways.. Because you are new Ill teach you a slow, inefficent but easy one.

here is the pseudocode:

    MainFunction()
    {
        loop while list is not empty
        { 
            String something = getFrom list
            print( reverseFunc(something) );
            nextValueinList();
        } 
    }
 
    String reverseFunc( String something )
    {
        String temporary = something;
        String result="";
        for( int i=temporary.size()-1; i>= 0; i-- )
        {
            result+=temporary.charAt( i );
        }
        return result;
    }
 

The function was not tested though but i guess you can make it run..

I was trying to work on the code but i keep getting the error
cannot find symbol
symbol : method size()
location: class java.lang.String
for(int i = (temp.size()-1);i>=0;i--)
I did import java.io and java.util in the beginning of the program.
thanks in advance :)

it worked!!!!! thankyou.
i changed the code a little bit..
for(int i = (temp.length() -1); i>=0;i--)

Size of arraylist is given by .size()
Length of string is given by .length()
