Question about the task Task No. 1 about integer type conversions
Java Syntax, Level 10, Lesson 4
Resolved
Why there is no "Arithmetic Error" when calculating d = (a + f/c +b) where byte c is actually 0 ?I specifically print out the result : System.out.println("f/c = " + f/c); //f/c = Infinity , where f is double but this will get ArithmeticException : System.out.println("d/c = " + d/c); // ArithmeticException : / by zero , where d is long Why there is a difference? Why both of them throw Arithmet

Help with access modifiers I solved the task relatively easily; however, I feel that my understanding of access modifiers is pretty fuzzy. If anyone can suggest any resources with a clear explanation of this concept, i'd appreciate it.

Struggling with this one When I run my program, it's not duplicating the word "love" even though I added to the list(at least that's what I thought I did). What is the problem? Thanks in advance.

Question about the task Task about algorithms
Java Syntax, Level 5, Lesson 12

The answer is wrong but why the lesson consider it right? The right answer should be 6, right? But this lesson consider 5 as true anyway. And now the code won't work. I think this solution broke the verification process of this lesson.

I can not get this to verify I have read through all the other questions and can not figure out why this will not pass. In my test file it prints correctly, it has no spaces at the end. I have used Math.round to round my numbers. It still will not pass verification.
