Answer:
private void printArray(int[] arr){ //0
System.out.print("["); //1
for(int k : arr){ //2
System.out.print(k + ", "); //3
}
System.out.println("]"); //4
}
Explanation:
This method should get you started. Your teacher may want a different format or a different type of loop. If you haven't learned for loops yet don't use them that'd be suspicious ;)
What I did:
0: This is the method heading with one parameter for the 1D array. If you need to access it in a different class change private to public.
1: This prints the [ with no line break
2: This is an enhanced for loop to iterate through each element in a 1D array. Alternatively, a normal for loop looks like this:
for (int i = 0; i < arr.length; i++)
instead of retrieving the variable with the enhanced for, you'd have to use arr[i] instead of k in this scenario.
3: This prints the value in each pass of the loop along with a comma and a space.
4: This adds the ] with a line break when the loop is completed
Hope this helps you get started :D comment if you need further help

Explanation:
Intrusion Detection System (IDS) monitors policy violations or malicious activities in a system or network. It could be a device or a software application.
IDS differs according to the size of the network. There are two main classifications: Host-based Intrusion Detection System (HIDS) and Network Intrusion Detection System (NIDS). HIDS observes important Operating System (OS) files. While the NIDS analyses network traffic, they are placed at a unique point or several unique points to monitor outgoing and incoming traffic within the network.
Hence it tries to identify unique sequences appearing across several packets in a traffic stream than in individual packets.
Answer:
In Java:
The method is as follows:
public static int countInRange (ArrayList<Integer> MyList, int min, int max) {
int count = 0;
for (int i = 0; i < MyList.size(); i++) {
if(MyList.get(i)>=min && MyList.get(i)<=max){
count++;
}
}
return count;
}
Explanation:
This defines the method
public static int countInRange (ArrayList<Integer> MyList, int min, int max) {
This declares and initializes count to 0
int count = 0;
This iterates through the ArrayList
for (int i = 0; i < MyList.size(); i++) {
This checks if current ArrayList element is between min and max (inclusive)
if(MyList.get(i)>=min && MyList.get(i)<=max){
If yes, increase count by 1
count++;
}
}
This returns count
return count;
}
To call the method from main, use:
countInRange(v,m,n)
<em>Where v is the name of the ArrayList, m and n are the min and max respectively.</em>
MS Excel is a spreadsheet programme developed by Microsoft in 1985, with the sole purpose of helping businesses compile all their financial data, yearly credit, and yearly debit sheets. Fast forward to the future after 31 years, it is now the most commonly used program for creating graphs and pivot tables.
