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:

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:

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.
