Answer: Stealth scanning technique
Explanation:
Stealth scanning technique consist of the following types of scans :
1. FIN scan
2. X- MAS tree scan
3. NULL scan
The FIN scan responds by considering port open if response in received for its packet sent with the fin flag else considered closed.
The X-MAS tree scan fires up by setting a TCP packet with URG, PUSH, FIN flags and the port is considered open if no response.
NULL scans sends null packet and considers it to be an open port.
Stealth scanning techniques considers to get some response from the network with out actually using a handshaking and is used to bypass firewall rules, logging mechanism, and hide themselves as usual network traffic.
Answer:
Explanation:
For the first questions the variable's name is <u>Today,</u> and is declared like a date variable, this will be returned a date value.
For the second question, where the browser will show today's date because with the variable Today, we get the date and with the document.write(Today) is shown the variable information.
With the third question, the result will be "Hello!", because the August is the 8 month, and July the 7, in this case the IF is False and for that will show "Hello!".

Answer:
import java.util.Scanner;
public class num5 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter The First String");
String str1 = in.next();
System.out.println("Enter The Second String");
String str2 = in.next();
System.out.println("Enter The Third String");
String str3 = in.next();
String oneAndTwo = str1+str2;
if(str3.equals(oneAndTwo)){
System.out.println(str1+" + "+str2+" is equal to "+str3+"!");
}
else
System.out.println(str1+" + "+str2+" is not equal to "+str3+"!");
}
}
Explanation:
- Implemented in Using Java Programming Language
- Import Scanner Class to prompt and receive users' input
- Create three string variables and store the three values entered by the user (str1, str2 and str3)
- Concatenate str1 and str2 using the + operator and assign to a new variable
- Use the if statement with Java's .equals() method to check for equality of the new string with the third string
- Print the appropriate message if the equal or not
