B = x is equal to 5
and
C = “ have special meaning and should not be used when naming variables “.
What is it about ? And what you need help on
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)
