understanding the java string with add operator

Question

I am trying to understand how the compiler views the following print statements. It is simple yet a bit intriguing.

This prints the added value. Convincing enough.<

Answer 1

I guess the Java specification explains it best:

The + operator is syntactically left-associative, no matter whether it is determined by type analysis to represent string concatenation or numeric addition. In some cases care is required to get the desired result. For example, the expression:

a + b + c

is always regarded as meaning:

(a + b) + c

So, if a was a String, then it concatenates with b. The result would be of String type, hence it continues to concatenate with c.
