Explanation:
A database management program (DBMS) is a software package design designed to manipulate, define, retrieve, and manage data in database.
A DBMS generally manipulates the data itself, the the data format, field names, record structure and file structure.
It means that it’s computer memory that needs power to keep the stored information. You can easily lose your data when the power is interrupted.
Answer:
- import java.util.Scanner;
-
- public class Main {
- public static void main(String[] args) {
- Scanner input = new Scanner(System.in);
-
- System.out.print("Input first string: ");
- String string1 = input.nextLine();
-
- System.out.print("Input second string: ");
- String string2 = input.nextLine();
-
- System.out.print("Start index for first string: ");
- int i1 = input.nextInt();
-
- System.out.print("Start index for second string: ");
- int i2 = input.nextInt();
-
- System.out.print("Number of characters to be compared: ");
- int n = input.nextInt();
-
- if(string1.regionMatches(true, i1, string2, i2, n)){
- System.out.println("The strings are equal.");
- }
- else{
- System.out.println("The strings are not equal.");
- }
- }
- }
Explanation:
The solution code is written in Java.
Firstly create a Scanner object (Line 5).
Next, use the Scanner object and nextLine method to get user input for string1 and string 2 (Line 7 - 11 )
Next, proceed to get the start index for first and second string using nextInt (Line 14 and Line 17) and followed with number of characters to be compared (Line 20).
Use the regionMatches method by passing all the input values as argument (Line 22) and if we pass the sample input we shall get the true and the program shall display the message "The strings are equal." (Line 22- 23)
So you don’t get black listed as spam for outgoing mail, and I hope this one is obvious - to make sure the server isn’t vulnerable to hackers and malware.
The technique is called serialization and deserialization.
