Explanation

When a string is concatenated with integers using the + operator, Java evaluates left-to-right. First "The answer is: " + 17 produces "The answer is: 17". Then that string is concatenated with 3 to produce "The answer is: 173". Once a string enters the expression, all subsequent + operations perform string concatenation, not arithmetic addition.
