Hey Guys, please I need help badly. Thank You

I read a text file from my hard disk which contains as follows...

void main()
{
int A = 5;
int B = 5;
int C ;
C = A + B;
cout << C ;
}

So, what I need to do is that..
Lets say I have an array of...

String []KeyWord = {"void", "main()"};
String []DataType = {"int", "float"};

So I want to loop through each token and check whether for example it's a key word or a datatype. I used java netBeans and I code as follows


int k = 0; int l = 0;

StringTokenizer Tokens;

while ((CurrentLine = ReadFile.readLine()) != null)
{
Tokens = new StringTokenizer(CurrentLine, " ", true);
for (int I = 0; Tokens.hasMoreTokens(); I++)
{
if (Tokens.nextToken().contains(KeyWord[k]))
{
jTextArea1.append(KeyWord[k] + "\n");
k++;


}
else if (Tokens.nextToken().contains(DataType[l]))
{
jTextArea2.append(DataType[l] + "\n");

}

}
}

I RECEIVE ERRORS I DON'T UNDERSTAND. PLEASE HELP ME GUYS THANKS...

You don't say what version of java you're using, I would recommend 7 if you can. What I would do is create a subclass of ArrayList as follows:

Code:

---

public class MyArrayList<E extends Object> extends ArrayList<E> {
        private static final long serialVersionUID = 1L;
       
        @SuppressWarnings("unchecked")
        public MyArrayList(Object[] array) {
                for(Object o : array)
                        this.add((E) o);
        }
}

---

You would then read a line in from your text file and split it on the spaces as follows:

Code:

---

try (Scanner in = new Scanner(new FileReader("/mytextFile.txt"))){

        while(in.hasNext()) {

                String[] line = in.nextLine().split(" ");
                List<String> line = new MyArrayList<String>(line);

                for(String kWord : KeyWord) {
                        if(line.contains(kWord)) {
                                //...do processing
                                break;
                        }
                }
                for(String dType : DataType) {
                        if(line.contains(dType)) {
                                //...do processing
                                break;
                        }
                }
        }
} catch(FileNotFoundException fnfe) {
        fnfe.printStackTrace();
}

---

Hope this helps.
