    <p>Sorry for the noob question. This is my first day trying out Java programming. I need help retrieving the users input of which operator the user wants to use with integers.</p> <pre><code>import java.util.Scanner; public class calculator { public static void main (String args[]) { Scanner number = new Scanner(System.in); double num1,num2,answer; char operator; System.out.println("Enter first number: "); num1 = number.nextDouble(); operator = number.nextChar(); /* the "nextChar" is not correct */ System.out.println("Enter second number: "); num2 = number.nextDouble(); if (operator = '+'){ answer = num1 + num2; /* If statements do not work like this */ } /* I would use "else if", unsure if it allows */ if (operator = '-'){ answer = num1 - num2; } if (operator = '*'){ answer = num1 - num2; } if (operator = '/'){ answer = num1 / num2; } System.out.println(num1 + num2 + operator + answer); } } </code></pre> <p>Edited Version:</p> <pre><code>import java.util.Scanner; public class calculator{ public static void main (String args[]) { Scanner userInput = new Scanner(System.in); String operator; double num1,num2,answer = 0; System.out.println("Enter first number: "); num1 = userInput.nextDouble(); System.out.println("Enter operator: "); operator = userInput.next(); System.out.println("Enter second number: "); num2 = userInput.nextDouble(); if (operator.equals ("+")){ answer = num1 + num2; } else if (operator.equals ("-")){ answer = num1 - num2; } else if (operator.equals ("*")){ answer = num1 * num2; } else if (operator.equals ("/")){ answer = num1 / num2; } System.out.println("First number:" + num1); System.out.println("Operator:" + operator); System.out.println("Second number:" + num2); System.out.println("Answer: " + answer); } } </code></pre> <blockquote> <p>First number:10.0</p> <p>Operator:*</p> <p>Second number:3.14</p> <p>Answer: 31.400000000000002</p> </blockquote> <p>Thanks a lot guys! Helped a lot!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
