In the System.out.println statement an addition is performed. with a string and a float.
So it simply adds these two like this

So the answer is true.
But if they use == the return value is false since the == checks whether it references to the same object (memory space) which is wrong.
When a String variable is declared it always create a new object(which is a String object).
String objects cannot be changed, they are immutable.
