Thread: Simple question with scanning strings

I'm new to java programming (about 1 week) and i've made up this simple program. The objective of the program is to make simple calculations but the problem is trying to input the operator. Here is the code:

import java.util.Scanner;
 
public class Main {
	public static void main(String args[]) {
		Scanner scanner = new Scanner(System.in);
 
		int num1,num2,result;
		String opr;
 
		System.out.println("Input 1st number:");
		num1 = scanner.nextInt();
 
		System.out.println("Now the operator:");
		opr = scanner.nextLine();
 
		if(opr.equals("+")) {
			System.out.println("Input 2nd number:");
			num2 = scanner.nextInt();
 
			result = num1 + num2;
			System.out.println("Result: " + result);
		}else if(opr.equals("-")) {
			System.out.println("Input 2nd number:");
			num2 = scanner.nextInt();
 
			result = num1 - num2;
			System.out.println("Result: " + result);
		}else if(opr.equals("*")) {
			System.out.println("Input 2nd number:");
			num2 = scanner.nextInt();
 
			result = num1 * num2;
			System.out.println("Result: " + result);
		}else if(opr.equals("/")) {
			System.out.println("Input 2nd number:");
			num2 = scanner.nextInt();
 
			result = num1 / num2;
			System.out.println("Result: " + result);
		}else{
			System.out.println("Please use a normal operator.");
		}
	}
}

What happens when i run the code is that it skips over scanning the opr variable and runs the else command. How can i fix this so i can input the operator?

Just a simple begginer question and it would be awesome if you could help me out.

problem is trying to input the operator

Please explain what problem you are having.

Please edit your post and wrap your code with code tags:

to get highlighting and preserve formatting.

There is a problem using the Scanner class's nextLine() method after nextInt().
