Answer:
mutator, accessor
Explanation:
Set methods are commonly called mutator methods, and get methods are commonly called accessor methods.
This is because set methods are used to mutate the state of a variable. Get methods, on the other hand are used to access the current state of the variable.
For example:
class Demo{
//Member variable
private int var;
//Accessor method
public int getVar(){
return var;
}
//Mutator method
public void setVar(int value){
var=value;
}
}
