How would I answer a question such as “what does the below expression evaluate to”.
"2 + 2 " + 3 + 4;
because I’m having a really hard time on the website practice-it and have tried everything from 2234 to 11 as possible answers.
In Java if either side of an addition is a string, the non-string operand is converted to a string and the two strings are concatenated. Never will a string be converted to an integer by using addition. Nor will a string containing an integer expression ever be evaluated.
So since addition is left-associative
"2 + 2 " + 3 + 4is parsed as("2 + 2 " + 3) + 4, which will evaluate to"2 + 2 3" + 4, which will in turn evaluate to"2 + 2 34".
