just been trying to convert a string into an Integer so that I can use it for something else but I keep falling into the null pointer exception trap.
public class ConvertToInt {
private InputReader reader;
public int changeToInteger(String word){
// Problem i've got is just below, I keep getting a null point exception on this line each time
// I want to return the result.
return reader.convertToInt(word); // null ponter exception on this line
}
}
parseInt method from InputReader class:
/**
* Convert the given word to an integer.
* @param word The word to be converted.
* @return The integer represented by word.
* @throws NumberFormatException if word is not an integer.
*/
public int convertToInt(String word)
{
return Integer.parseInt(word);
}
