Question

Create a JAVA program that in two numbers from user input, the program then does the following arithmetic calculations. The program will run in ascending order if the first number is small and in descending order of the first number is bigger. The program then alternates between addition(ODD) and subtraction(EVEN) depending on the previous number see examples below   [15]

Sample run 1:
Enter two numbers: -3 2

Output:

The following arithmetic calculations were performed :

Arithmetic operations = (-3) + (-2) - (-1) + 0 - 1 + 2

Result = -3

Sample run 2:
Enter two numbers: 4 1

Output:

The following arithmetic calculations were performed :

Arithmetic operations = 4 - 3 + 2 - 1

Result = 2

Answer 1

#source code:

import java.util.*;

public class Sample{

public static void main(String args[]){

Scanner SObj=new Scanner(System.in);

int a,b;

a=SObj.nextInt();

b=SObj.nextInt();

int out=0;

if(a>b){

out=a;

a=a-1;

while(a>=b){

if(a%2==0){

out=out+a;

}else{

out=out-a;

}

a=a-1;

}

}else if(a<b){

out=a;

a=a+1;

while(a<=b){

if(a%2==0){

out=out+a;

}else{

out=out-a;

}

a=a+1;

}

}

System.out.println(out);

}

}

#output:
