    <p>I've been learning about enums and switch statements and I have the following code</p> <p>I dont want to run arguments through code, then compile it to see the result, I want a user to input numbers into terminal and +,x,/,- and to get a result back in terminal, how can I accomplish this</p> <pre><code>public class MathCalculatorTest2_0 { MathFunctions1_0 mathFunction1; public MathCalculatorTest2_0 (MathFunctions1_0 mathFunction1) { this.mathFunction1 = mathFunction1; } public void DoMath(double digit1, double digit2) { double mathResult = 0; switch (mathFunction1) { case MULTIPLY: mathResult = digit1*digit2; break; case DIVIDE: mathResult = digit1/digit2; break; case ADD: mathResult = digit1+digit2; break; case SUBTRACT: mathResult = digit1-digit2; break; default: System.out.println("Incorrect arithmatic character, please insert a correct arithmatic character between the two numbers (x, /, +, -)"); } System.out.println(mathResult); } public static void main(String[] args) { if (args.length &lt; 3) { System.out.println("Please correct syntax"); } else { double firstDigit = Double.parseDouble(args[0]); String userInput1 = args[1]; double secondDigit = Double.parseDouble(args[2]); MathCalculatorTest2_0 C; switch (userInput1) { case "x": C = new MathCalculatorTest2_0(MathFunctions1_0.MULTIPLY); C.DoMath(firstDigit, secondDigit); break; case "/": C = new MathCalculatorTest2_0(MathFunctions1_0.DIVIDE); C.DoMath(firstDigit, secondDigit); break; case "+": C = new MathCalculatorTest2_0(MathFunctions1_0.ADD); C.DoMath(firstDigit, secondDigit); break; case "-": C = new MathCalculatorTest2_0(MathFunctions1_0.SUBTRACT); C.DoMath(firstDigit, secondDigit); break; default: System.out.println("Please insert correct arithmatic character."); } } } </code></pre> <p>}</p> <pre><code>public enum MathFunctions1_0 { MULTIPLY, DIVIDE, ADD, SUBTRACT </code></pre> <p>}</p>

    1. COfirst have a look at this : http://docs.oracle.com/javase/tutorial/java/nutsandbolts/switch.html second : dont name variables starting with capital letters. third : give meaningful names (class name/ instance names here)

    3. COhi thank you for the comments, however I'm very new to Java and I'm not a computer science major, I never took a class... so I don't know how to better design anything yet... please dont be so critical. Also, how does this help me get a user to input 10x10 and get 100 as a result?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
