Answer:
A) Switch
Explanation:
In Java and most programming Languages, A Switch Statement provides a multi branch statements which provides a more flexible way for transfer of execution to the branch that fulfills the condition of the expressed value. This is a better way of handling if...elseif....else statements. In this way, a variable is tested for equality against some values. Variables used in switch expressions can only be primitives (int, byte, char), enums and strings. A switch statement has
1. A default statement (optional), appears at the end of the switch and acts as the else condition.
2. A break statement which terminates the switch when reached.
The syntax of a switch statement is given below:
switch(expression) {
case x:
// code block
break;
case y:
// code block
break;
default:
// code block
}
you would have to call all of them, so d.

Answer:
laser
Explanation:
These are well known printer types now. Let's review how they work to determine in which does heat plays a role.
inkjet: inkjet printers are printer throwing ink at the paper in the form of little drops. No heat involved here.
impact: That's the oldest technology, where a printing head is moving left and right to punch a printing ribbon and transfer ink onto the paper. No heat involved.
3D: 3D printers don't usually use paper... as they use other materials to create a 3D representation of a model. Heat is involved in the melting of the material before it's placed on the building model. But no paper involved here.
laser: laser printers are working very much like a photocopier machine... memorizing the pattern to be printed, then transferring it onto paper... using heat.
