Use of the world's a+b function

Figure 5 shows source code resulting from the use of the a + b function to concatenate two strings.

Figure 5. Sample string-concatenation code. 
public void main ( ) {
  String myFirstName = John-; 
  String myLastName = Jones; 
  String y = default string;
    y .set(value,(myFirstName + myLastName));
  print( y );
}

The code would join the two strings producing the following output text:

the value of world.main.y is John-Jones
