Answer:
Instantiate the object and access the variable using object reference.
Explanation:
In order to use/access an instance variable in a class, the class needs to be instantiated.For example:
class Demo{
//Instance variable declaration
int testvar=0;
public static void main(String args[]){
//Class instantiation
Demo d = new Demo();
// The instance variable is accessed using the object reference
d.testvar = 1;
}
}
In case the instance variable in private then it can be accessed using its corresponding getter/setter methods.
Answer:
Tuning. See explanation below.
Explanation:
Tuning
By definition the tuning is: "the process of adjusting an IDPS to maximize its efficiency in detecting true positives, while minimizing both false positives and false negatives."
And this process is the improvement of system performance in computer science. Usually is related to optimization of a process, when we us tunning, we can follow these steps:
a) Identify which numeric values are acceptable and improve the parameters
b) Take a measure for the system originally and without the tunning in order to have an initial comparative measure
c) Understand that each process have a critical path, we need to identify it.
d) Modify parts who not improve the efficiency of the algorithm
e) Check the performace when we apply modifications
