You are developing a complex PL/SQL routine. Which of the following control structures in PL/SQL can be used for unconditional branching to a particular area of the code block?

Derive a class TimedPosition to represent a kind of three-dimensional position that includes all of Position3D’s attributes and an additional attribute called time (an integer). Include a default constructor and a four-parameter constructor that initializes all four components. You may assume that a definition already exists for Position3D's three-parameter constructor.

What will be an ideal response?

What will be output from the following code:

``` public void t e s t 7 ( ) { int x = 1 2 ; int y = 0 ; while ( x < 10 j j y < 1) { x = x + 1 ; y = y + 1 ; System . out . p r i n t l n ( x + " , " + y ) ; } } ```
