Consider the following method, which is intended to return the product of 3 and the nonnegative difference between two int parameters.
public int threeTimesDiff(int num1, int num2) {
return 3 * (num1 - num2);
}
Which precondition is required so that the method works as intended for all values of the parameters that satisfy the precondition?
A. num1 > 0, num2 > 0
B. num1 >= 0, num2 >= 0
C. num1 >= num2
D. num2 >= num1
Methods are code segments that are executed when called or evoked.
The required precondition for the method to work as intended is (c) num1 >= num2
The return value of the method is given as:
3 * (num1 - num2).
The return value is said to be non-negative.
So, the following condition must be true
[tex]3 \times (num1 - num2) \ge 0[/tex]
Divide both sides of the equation by 3
[tex](num1 - num2) \ge 0[/tex]
Remove the bracket
[tex]num1 - num2 \ge 0[/tex]
Add num2 to both sides of the equation
[tex]num1 \ge num2[/tex]
Hence, the required precondition for the method to work as intended is (c) num1 >= num2

The voltage/potential difference in a circuit is 12 volts, calculate the current that is flowing through the circuit if the resistance is 48 Ohms.
Current (I) = 0.25 ampere (A)
Power (P) = 3 watt (W)
Current (I) = 0.25 ampere (A) Power (P) = 3 watt (W) Steps: I = V R = 12 volt 48 ohm = 0.25 ampere (A) P = V2 R = (12 volt)2 48 ohm = 3 watt (W)
When the logging and managing information flow between management hosts and the managed devices travels on a dedicated management network, this is considered what?
What must be considered is the number of IPs that are allowed to access the management network.
We can arrive at this answer because:
During the management of information flow, it is necessary to guarantee the security of the system, preventing intruders from attacking.This can be done by restricting authorized IPs to access the management interface.This type of security measure is often neglected in systems that use a dedicated management network, as this type of network can only be accessed by a single device in the same VLAN.However, the IPs restriction must be considered even in this system, as there are software that can provoke invasions that cause the leak of shared information.

The complete program is to define a boolean method that returns true if all elements of an array are negative, or return false, if otherwise
The method in java, where comments are used to explain each line is as follows:
//This defines the method
public static boolean chkNegative (double[] myArr) {
//This initializes a boolean variable
boolean isNeg = true;
//This iterates through the array
for (int i = 0; i < myArr.length; i++) {
//If the array element is 0 or positive
if (myArr[i] >= 0) {
//Then the boolean variable is set to false
isNeg = false;
//And the loop is exited
break;
}
}
//This returns true or false
