Java If Statement issue [duplicate]

This question already has an answer here:

• How do I compare strings in Java? 23 answers

I have this code in Java to give some information about either a circle, a triangle or a quadrilateral. I have specified an if statement, which I'm going to add more information to.

I don't know whether an if statement is the right way to let the user choose if he wants to have information about a circle, triangle or rectangle. Because I actually wanted to have some kind of buttons each for the circle, triangle and rectangle. So if you have any tips on that I would really appreciate it.

This is the code I'm having trouble with, everytime I type in 'cirkel' which I have mentioned in the if statement, it goes on to the else statement and I get a dialog saying 'bye'.

import java.util.*;
import javax.swing.JOptionPane;

public class Vormen {

    public static void main(String[] args){
        String vorm;
        double diameter;
        double r;
        double omtrek;
        double oppervlakte;

        Scanner keyboard = new Scanner(System.in);
        vorm = JOptionPane.showInputDialog("Kiest u voor de 'cirkel', 'driehoek' of 'vierhoek'?");

        if (vorm == "cirkel"){
            diameter = diameter = Double.parseDouble(JOptionPane.showInputDialog("Wat is de diameter van de cirkel (in m)"));
            r = diameter / 2;
            omtrek = 2 * Math.PI * r;
            oppervlakte = Math.PI * r * r;
            JOptionPane.showMessageDialog(null, "De straal = " + r + " m\n\n" + "De omtrek = " + omtrek + " m\n\n" + "De oppervlakte = " + oppervlakte + " m^2");
        }

        else {
            JOptionPane.showMessageDialog(null, "bye");
        }

    }

}

Thanks in advance!

tcl non curly braces expression slower than with them?

I have noticed something. Let's look at two codes bit. in 1, if is not input with a curly brace input, the other is. The curly braced 1 is slightly faster. Why?
See codes and outputs below:

puts [ time { if { [ expr { 5 % 2 } ] } { puts 1 } else { puts 2 } } ]
1
52 microseconds per iteration
puts [ time { if [ expr { 5 % 2 } ] { puts 1 } else { puts 2 } } ]
1
54 microseconds per iteration

The differences are stable. 2 microseconds faster when using more code characters.
Why?

Python: i'm having an issue with my if else statement

My if and else statement works but when i press the button i created for it, i get no results from it and i am not sure if its the cmds.setKeyframe i have set up within the statement thats causing the issue.

class Shells(object):  
def __init__(self): #initializing the class ShellsUI
    self.Shells = [] #empty list
    self.currentX = 0 # this is where the ball is placed
    self.space = 4 # spacing of the cups

    #Test to see if the window exists
    if cmds.window('ShellsWin', exists=True):
        #delete the window

    #    key is pressed. Hitting just the Return key will keep focus

How do I sum results of two if statements in the same cell?

I'm looking to have the results of two If statements calculated and added in the same cell. I'm getting #VALUE! error.

=SUM(IF(ISERROR(GETPIVOTDATA("Sum of CHARGES",'Ship City'!$A$3, "ship_city",$B$7,"carrier_type",$A$27, "INV_month_id",D$6,"INV_year_id",$D$5,"Company Name",$B29)),"",GETPIVOTDATA("Sum of CHARGES",'Ship City'!$A$3, "ship_city",$B$7,"carrier_type",$A$27, "INV_month_id",D$6,"INV_year_id",$D$5,"Company Name",$B29))+IF(ISERROR(GETPIVOTDATA("Sum of CHARGES",'Recipient City'!$A$4, "recipient_city",$B$7,"carrier_type",$A$27, "INV_month_id",D$6,"INV_year_id",$D$5,"Company Name",$B29)),"",GETPIVOTDATA("Sum of CHARGES",'Recipient City'!$A$4, "recipient_city",$B$7,"carrier_type",$A$27, "INV_month_id",D$6,"INV_year_id",$D$5,"Company Name",$B29)))

Same row different column. Excel Formula

If is possible with the if(indirect formula to give me the value from the same row but from a different column if a specific cell is from that row?

More specific: I want cell =Sheet2!F23 to give me =Sheet1!N11 if =sheet2!C23 is from Sheet1!B11. The important thing is the I need it to come from row 11 but from a different column.

Thanks in advance.

execute if statement in variable value assignement powershell

Sometimes I need to check if a pathname ends with "\" adding it if necessary, the code is pretty simple, something like this

if ($destFolder[-1] -ne '\') {
    $destFolder += '\';
}

Is there a way to evaluate an if statement inside () so that I can use it in variable assignement? I mean something like this

$finalName = $destFolder + (if ($destFolder[-1] -ne '\') { '\' } ) + $fileName

Given that if is not a cmdlet I get this error

if : The term 'if' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

If else error I don't understand this error

I don't understand this error is it logical error or something else here is the coding " this program should convert riyal to currency that is chosen by the user using multiway if-else

import java.util.Scanner;
