i think i.m close...but
public class Tweet {
private String text;
public static final int MAX_CHARS = 140;
public int result;
public int getRemainingCharacterCount(){
result = MAX_CHARS - text.length();
if(result>=0){
return result;

The problem is here
public int getRemainingCharacterCount(){
result = MAX_CHARS - text.length();
if(result>=0){
return result;
}
}
what if the 'if' statement is false? what is being returned?
you need an else
or you can return some default value, depending on what the challenge is asking you to doo
example
public int getRemainingCharacterCount(){
result = MAX_CHARS - text.length();
if(result>=0){
return result;
} else{ retun 1}
}
or
public int getRemainingCharacterCount(){
result = MAX_CHARS - text.length();
if(result>=0){
return result;
}
return 1
}
these are just examples to point you into the right direction
if this answers your question, please mark the question as answered.

Courses Plus Student 16,751 Pointshello, the problem, is there is no need of a if statement, we just need to return a value.. in this particular case, i found out this simple solution:
public int getRemainingCharacterCount(){ return MAX_CHARS - text.length();
}

14,132 Pointsnope ... your code is not correct. you must account for a case when result < 0. What happens then?

Courses Plus Student 16,751 Pointswell i check back my solution, and it works...i mean passed the challenge....so i can not understand, why you said that my code it is worng??, may be not perfect, not the best solution, but works... did you really try my way?.. regards Mark

Courses Plus Student 16,751 Pointsyou are right, but on the challenge request, the scope for me, is "return the value" not a validation, as you probably thinking correctly by the way....but for a starting guy like me the challenge it is covered with the small code...
