    <p>I am new around here but let's get straight to the question: When I was writing the following code for a class project calculator I came across a "token error". This is the full error message:</p> <pre><code>Exception in thread "main" java.lang.Error: Unresolved compilation problem: Syntax error on token "else", delete this token at calculatorApplet.main(calculatorApplet.java:42) </code></pre> <p>I wrote this code:</p> <pre><code>import java.util.Scanner; import javax.swing.JOptionPane; public class calculatorApplet { Scanner sc = new Scanner(System.in); public static void main(String[] args) { JOptionPane.showMessageDialog(null, "Welcome to the Calculator!"); String option = JOptionPane.showInputDialog(null, "Which calculator mode do you want?"); if (option.equals("Addition")) { Double add1 = Double.parseDouble(JOptionPane.showInputDialog(null, "Okay type the first number(s) of your addition problem.")); Double add2 = Double.parseDouble(JOptionPane.showInputDialog(null, "Now type the second number(s) of your addition problem.")); Double preAdd = add1+add2; Double Add = preAdd; JOptionPane.showMessageDialog(null, "The sum is " + Add + "."); } else { JOptionPane.showMessageDialog(null, "Huh?"); } if (option.equals("Subtraction")) { Double sub1 = Double.parseDouble(JOptionPane.showInputDialog(null, "Okay type the first number(s) of your subtraction problem.")); Double sub2 = Double.parseDouble(JOptionPane.showInputDialog(null, "Now type the second number(s) of your subtraction problem.")); Double preSub = sub1-sub2; Double Sub = preSub; JOptionPane.showMessageDialog(null, "The difference is " + Sub + "."); } else { JOptionPane.showMessageDialog(null, "Huh?"); } if (option.equals("Multiplication")); { Double mult1 = Double.parseDouble(JOptionPane.showInputDialog(null, "Okay type the first number(s) of your multiplication problem.")); Double mult2 = Double.parseDouble(JOptionPane.showInputDialog(null, "Now type the second number(s) of your multiplication problem.")); Double preMult = mult1*mult2; Double Mult = preMult; JOptionPane.showMessageDialog(null, "The product is " + Mult + "."); } else //Here is the error. { JOptionPane.showMessageDialog(null, "Huh?"); } //Here ends the error. if (option.equals("Division")) { Double div1 = Double.parseDouble(JOptionPane.showInputDialog(null, "Okay type the first number(s) of your division problem.")); Double div2 = Double.parseDouble(JOptionPane.showInputDialog(null, "Now type the second number(s) of your division problem.")); Double preDiv = div1/div2; Double Div = preDiv; JOptionPane.showMessageDialog(null, "The quotient is " + Div + "."); } else { JOptionPane.showMessageDialog(null, "Huh?"); } //End of if statements. } } </code></pre> <p>That's the code and I commented the area where the token error is. Maybe the solution is right in my face. I want my code to be a calculator so if you guys can fix my code to not conflict with the math operations. Thanks and I appreciate any help.</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.
