Java weirdness
“In Java, int x = 5; x += 2.5; works (x is now 7), whereas int x = 5; x = x + 2.5; gives a type error.”
The first one to explain this wins a free beer ..

Compound operators do implicit casting for you –> x +=2.5 so your double is casted to int.
While arithmetical operation x+2.5 has to result to integer, so you have to explicitly cast to (int)2.5 –> x= x + (int)2.5
What is says – both statements are not equivalent and can produce different results.
I agree this is a weird.
You, sir, just won a beer!
Let me know where you live, next time I’m in canada
