pls help someone :) This is my problem: Let's let them know how many characters they have left to use...so they can jam them full of hashtags #jklol
Create a public method named getRemainingCharacterCount that returns an int representing how many characters they have left before they 140. Base your calculation on the field that stores the current text.
public class Tweet {
public static final int MAX_CHARS = 140;
private String text;
public Tweet(String text) {
this.text = text;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public int getRemainingCharacterCount() {
//i tried this but i know it is not good --> return MAX_CHARS - text.lenght();
}
}

this worked for me... I added text = ""; to the first method. Also, check the spelling of length. That was getting me for awhile.

public int getRemainingCharacterCount() {
return MAX_CHARS - (text != null ? text.length() : 0);
}
