When the user selects the multiple check boxes I need to execute the following with the same name. How to use the for loop condition for this?
I tried to use the if-else if but only one selection gets executed. Is there any way to implement for loop to reduce the code length?
I am using JFrame absolute layout so the checkbox variables already get pre-defined. I can't able to use an array.

If you use else if it will stop executing further cases as soon as one if returns true. One way to maybe reduce your code a bit would be by adding all the Checkboxes to an ArrayList and then loop through that.
List<JCheckBox> cbList = new ArrayList<>();
JCheckBox chckbxNewCheckBox = new JCheckBox("US");
chckbxNewCheckBox.setBounds(17, 94, 63, 23);
contentPane.add(chckbxNewCheckBox);
cbList.add(chckbxNewCheckBox);
JCheckBox chckbxNewCheckBox_1 = new JCheckBox("UK");
chckbxNewCheckBox_1.setBounds(104, 94, 63, 23);
contentPane.add(chckbxNewCheckBox_1);
cbList.add(chckbxNewCheckBox_1);
JCheckBox chckbxNewCheckBox_2 = new JCheckBox("IN");
chckbxNewCheckBox_2.setBounds(177, 94, 72, 23);
contentPane.add(chckbxNewCheckBox_2);
cbList.add(chckbxNewCheckBox_2);
JCheckBox chckbxNewCheckBox_3 = new JCheckBox("JP");
chckbxNewCheckBox_3.setBounds(17, 133, 63, 23);
contentPane.add(chckbxNewCheckBox_3);
cbList.add(chckbxNewCheckBox_3);
JCheckBox chckbxNewCheckBox_4 = new JCheckBox("FR");
chckbxNewCheckBox_4.setBounds(104, 133, 63, 23);
contentPane.add(chckbxNewCheckBox_4);
cbList.add(chckbxNewCheckBox_4);
JCheckBox chckbxNewCheckBox_5 = new JCheckBox("DE");
chckbxNewCheckBox_5.setBounds(177, 133, 72, 23);
contentPane.add(chckbxNewCheckBox_5);
cbList.add(chckbxNewCheckBox_5);
JCheckBox chckbxNewCheckBox_6 = new JCheckBox("ES");
chckbxNewCheckBox_6.setBounds(17, 174, 63, 23);
contentPane.add(chckbxNewCheckBox_6);
cbList.add(chckbxNewCheckBox_6);
JCheckBox chckbxNewCheckBox_7 = new JCheckBox("IT");
chckbxNewCheckBox_7.setBounds(104, 174, 63, 23);
contentPane.add(chckbxNewCheckBox_7);
cbList.add(chckbxNewCheckBox_7);
JCheckBox chckbxNewCheckBox_8 = new JCheckBox("CA");
chckbxNewCheckBox_8.setBounds(177, 174, 72, 23);
contentPane.add(chckbxNewCheckBox_8);
cbList.add(chckbxNewCheckBox_8);
Alexeys comment got me thinking about checking wether or not any Checkboxes were selected, which might be useful to check at first.
private boolean selectionWasMade()
{
int selectedCounter = 0;
for(JCheckBox checkbox : cbList)
{
if(checkbox.isSelected())
{
selectedCounter++;
}
}
if(selectedCounter != 0)
{
return true;
}
return false;
}
Now you simply check if this returns true and execute this loop:
if(selectionWasMade())
{
for(JCheckBox checkbox : cbList)
{
if(checkbox.isSelected())
{
aru.findElement(By.id("name")).sendKeys("SNS - Checkout Preflight - Desktop - " + checkbox.getText() + " - "+content);
}
}
}
else
{
JOptionPane.showMessageDialog(null, "Please select from list");
}
Hope I could help, my answer should be all cleaned up and correct now after several edits!

I have a JComboBox that retrieves it's data from a database (Ahmed, Mahmoud, Ali).
when I select the first option, it displays the information of Ahmed that I retrieved from the database and shown in a JFrame as text of a JLabels
The problem is that when I choose the second option, it overwrites the informations of Ahmed with Mahmoud's and display it above.

try to use calendarPanel.removeAll(); before to remove all components

I've setup a simple GUI system to use this XOR encryption system. When I decrypt through the GUI the decryption comes out wrong, but when I hard-code the string to decrypt it comes out right. For example:
For example, this prints "this_is_to_test_if_the_program_in_the_gui_is_working_which_it_wont":
System.out.println(Skeleton.xorDecrypt("BX_Dg_CgLVkCVKLfQUfC^SgHFWSFY^oP]iBPShSC]g^KgO[D\\Q]Qg#PQTPk^MiA_VD", "638460047789894"));
But if I do it through the GUI it comes out as "this_is_to_test_if_the_program_in_the_gui_is_workdiia_xdglf\g{Qykns"

I have a client and server. Server sends some questions to the Client. In client side I want to display these questions on a SWT application window.
