Thread: Dividing by Zero Issue ( Project - Cant figure out how to do it, or why mine is not working )

[ SOLVED ]

So, I'm trying to have the program display " You can not divide by zero " When the user divides by zero. ive read my book that i have ( purchased from school) - And i cant figure it out.

Once the user Enters " 4 " as the menuNumber - It goes into the calculator as being a division problem.

Im not really sure how to approach this, thus why i need some help.
I will be posting the full code below. Im not sure if i shouldnt, but i really cant figure this out D:

" import java.util.Scanner;
 
 
public class BasicCalculator {
	// Main menu
	public static void main(String[] args) {
	//Create Scanner
				Scanner input = new Scanner(System.in);	
 
 
	System.out.println("Menu: ");
	System.out.println("1. Add ");
	System.out.println("2. Sub ");
	System.out.println("3. Multiply ");
	System.out.println("4. Divide ");
	System.out.println("5. Generate a Random Number");
 
	// Complete the input on what you would like to do. 
	System.out.println(" What would you like to do?");
	int menuNumber = input.nextInt();
	if (menuNumber < 1 ) {
		System.out.println("Im Sorry, You must choose Between 1 and 5.");
	}
	if (menuNumber > 5 ) {
		System.out.println("Im Sorry, You must choose Between 1 and 5.");
	}
	if (menuNumber == 1) {
		System.out.println("What is the first Number?:");
	int number1 = input.nextInt();
		System.out.println("What is the Second Number?:");
	int number2 = input.nextInt();
	int answer = number1 + number2;
		System.out.print("Answer : "+answer  );
	}
	if (menuNumber == 2) {
		System.out.println("What is the first Number?:");
	int number1 = input.nextInt();
		System.out.println("What is the Second Number?:");
	int number2 = input.nextInt();
	int answer = number1 - number2;
	System.out.print("Answer : " +answer  );
	}
	if (menuNumber == 3){
		System.out.println("What is the first Number?:");
	int number1 = input.nextInt();
		System.out.println("What is the Second Number?:");
	int number2 = input.nextInt();
	int answer = number1 * number2;
	System.out.print("Answer : " + answer  );
	}
	if (menuNumber == 4){
		System.out.println("What is the first Number?:");
	int number1 = input.nextInt();
		System.out.println("What is the Second Number?:");
	int number2 = input.nextInt();
	System.out.print("Answer : " + number1 / number2);
 
	if  (number2 <= 0) {
			System.out.println("You can Not divide by zero.");
	} 
	}
	if (menuNumber == 5){
		System.out.println("What is the lower limit?:");
	int min = input.nextInt();
		System.out.println("What is the upper limit?:");
	int max = input.nextInt();
 
	int answer = (int) (Math.ceil(Math.random() * (max - min)) + min);
 
 
	System.out.println("Answer: " + answer);
	}
	}
	}
"

Now everything works- I just cant figure out the diving by zero issue.
If you have a link to a page that will help me, please do. I would like to understand what i need to do.

how to get it to display " I'm sorry, you cannot divide by zero " when the user trys to divide by zero.

That sounds what could be done with an if statement. Have you tried that?
