## What are the 5 logical operators?

## Can you use += in Java?

As long as x and y are of the same type (for example, both are int s), you may consider the two statements equivalent. However, in Java, x += y is not identical to x = x + y in general. += performs an implicit cast, whereas for + you need to explicitly cast the second operand, otherwise you’d get a compiler error.
