Answer:
The program is as follows:
import java.util.*;
public class Main{
public static void process(char ch, int x, int y){
if(ch == '+'){
System.out.print(x+y); }
else if(ch == '-'){
System.out.print(x-y); }
else if(ch == '*'){
System.out.print(x*y); }
else if(ch == '/'){
if(y!=0){
double num = x;
System.out.print(num/y); }
else{
System.out.print("Cannot divide by 0"); } }
else{
System.out.print("Invalid operator"); }
}
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int x, y;
char ch;
System.out.print("Enter two integers: ");
x = input.nextInt(); y = input.nextInt();
System.out.print("Enter operator: ");
ch = input.next().charAt(0);
process(ch,x, y);
}
}
Explanation:
The function begins here
public static void process(char ch, int x, int y){
If the character is +, this prints the sum of both integers
<em> if(ch == '+'){</em>
<em> System.out.print(x+y); }</em>
If the character is -, this prints the difference of both integers
<em> else if(ch == '-'){</em>
<em> System.out.print(x-y); }</em>
If the character is *, this prints the product of both integers
<em> else if(ch == '*'){</em>
<em> System.out.print(x*y); }</em>
If the character is /, this prints the division of both integers.
<em> else if(ch == '/'){</em>
<em> if(y!=0){</em>
<em> double num = x;</em>
<em> System.out.print(num/y); }</em>
<em> else{</em>
<em>This is executed if the denominator is 0</em>
<em> System.out.print("Cannot divide by 0"); } }</em>
Invalid operator is printed for every other character
<em>else{</em>
<em> System.out.print("Invalid operator"); }</em>
<em> </em> }
The main begins here
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
This declares both integers
int x, y;
This declares the operator
char ch;
Get input for both integers
<em> System.out.print("Enter two integers: ");</em>
<em> x = input.nextInt(); y = input.nextInt();</em>
Get input for the operator
<em> System.out.print("Enter operator: ");</em>
<em> ch = input.next().charAt(0); </em>
Call the function
process(ch,x, y);
}
}
