a hard copy stores data and information in the form of physical files it may be images text photographs and more a soft copy data and information in the form of virtual file saved on a computer or a drive you can preserve a hard copy for two long because its day subjected to wear and tear
Answer:
- import java.util.Scanner;
- public class num8 {
- public static void main(String[] args) {
- int first, second, third, fourth,total;
- double decimalOne, decimalTwo, decimalTotal;
- }
- public static void getData(int first, int second, int third, int fourth, double decimalOne, double decimalTwo){
- System.out.println("Enter the Values");
- Scanner in = new Scanner(System.in);
- first=in.nextInt();
- second=in.nextInt();
- third=in.nextInt();
- fourth=in.nextInt();
- decimalOne = in.nextDouble();
- decimalTwo = in.nextDouble();
- }
- public static int computeTotal(int first, int second, int third){
- return first+second+third;
- }
- public static int computeTotal(int first, int second, int third, int fourth){
- return first+second+third+fourth;
- }
- public static double computeTotal(double decimalOne, double decimalTwo){
- return decimalOne+decimalTwo;
- }
- public static void printAll( int first, int second, int third){
- System.out.println("Number one, two and three are: "+first+" "+second+" "+third);
- }
- public static void printAll( int first, int second, int third, int fourth){
- System.out.println("Number one, two and three and four are: "+first+" "+second+
- " "+third+" "+fourth);
- }
- public static void printAll( int first, int second, int third, int fourth, int fifth){
- System.out.println("Number one, two and three and four are: "+first+" "+second+
- " "+third+" "+fourth+" "+fifth);
- }
- public static void printAll( double first, double second, double third){
- System.out.println("Number one, two and three and four are: "+first+" "+second+
- " "+third);
- }
- }
Explanation:
This solution is provided in Java:
All the variable declarations are done in the main method (lines 3-6)
Eight methods as specified in the question are created (Lines 7, 17, 20, 23, 26, 29, 33 and 37).
Observe the concept of Method Overloading (i.e. methods with same name and return types but different parameter list)
Answer:
Advantages :
Management of hardware and software
easy to use with GUI
Convenient and easy to use different applications on the system.
Disadvantages:
They are expensive to buy
There can be technical issues which can ruin the task
Data can be lost if not saved properly
Explanation:
Operating system is a software which manages the computer. It efficiently manages the timelines and data stored on it is considered as safe by placing passwords. There are various advantages and disadvantages of the system. It is dependent on the user how he uses the software.
