Consider having three String variables a, b, and c. The statement c = a + b; also can be achieved by saying
A) c = a.length( ) + b.length( );
B) c = (int) a + (int) b;
C) c = a.concat(b);
D) c = b.concat(a);
E) c = a.plus(b);

Question

Quizplus · Accepted Answer

C) The statement c = a + b uses the concatenation operator + (not to be confused with numeric addition). The same result can be achieved by passing a the concat message with b as the parameter. Answer D will set c to be b + a rather than a + b.
