TASK 5. Methods Overloading. Review Methods, Implement the following code, test it with different input, make sure it runs without errors.

Solution:

Java code:

Main.java

import java.util.Scanner;

public class Main{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);

// Prompt the user to enter number of Integer
System.out.println("Enter the number of integers you will provide: ");
int num = sc.nextInt();

// Prompt the user to enter first Integer
System.out.println("Enter the value of \'a\' and press Enter: ");
int a = sc.nextInt();

// Prompt the user to enter second Integer
System.out.println("Enter the value of \'b\' and press Enter: ");
int b = sc.nextInt();

if(num >= 3){

// Prompt the user to enter third Integer
System.out.println("Enter the value of \'c\' and press Enter: ");
int c = sc.nextInt();

if(num == 3){

// Display result of three number sum
System.out.printf("Provided Integers: %4d and %4d and %4d, the total is %5d\n",a, b, c ,sum(a, b, c));
}
else if ( num== 4){

System.out.println("Enter the value of \'d\' and press Enter: ");
int d = sc.nextInt();
// Display result for four number sum
System.out.printf("Provided Integers: %4d and %4d and %4d and %4d, the total is %5d\n",a, b, c, d ,sum(a, b, c, d));
}
}
else{

// Display result of 2 number sum
System.out.printf("Provided Integers: %4d and %4d, the total is %5d\n",a, b,sum(a, b));
}

}

//this method return the sum of two number
public static int sum(int num1, int num2){
return num1+num2;
}

//this method returns the sum of three numbers
public static int sum(int num1, int num2, int num3){
return num1+num2+num3;
}

//this method returns the sum of four numbers
public static int sum(int num1, int num2, int num3, int num4){
return num1+num2+num3+num4;
}
}
