Question

Dear stackoverflow members,
I have a small problem,

I want to replace some characters in my string with other in java, and my code to do it is as follow,

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         

jComboBox1.removeAllItems();
String str =  new GenericResource_JerseyClient().getlist();
    String [] temp = null;
    temp = str.split(",");
     temp[1]=temp[1].replaceAll("'", "");
    temp[1]=temp[1].replaceAll(" ", "");
    temp[1]=temp[1].replace("[", "");
    temp[1]=temp[1].replace("]", "");

     for(int i =0; i < temp.length ; i++)
     {
         jComboBox1.addItem(temp[i]);
     }        // TODO add your handling code here:      // TODO add your handling code here:
                // TODO add your handling code here
    }  

As it can be seen from the above code i replace “‘”,”[“,”]”,and empty space with nothing.
As it can be also seen from the code that i split the string into two. In the part of string after , the code works well but the part of string before , the code doesn’t seem to work properly.
i have also attached a copy of the dropdown list output in the client side.

Any help would be very much appreciated on how to remove [ and ‘ from the string.

Cheers.

Perform all your replacements BEFORE splitting the string. This is better than executing the same code in a loop.

For example:

String cleanString = str.replace("'", "").replace(" ", "").replace("[", "").replace("]", "");
String[] temp = cleanString.split(",");
for(int i = 0; i < temp.length ; i++) {
    jComboBox1.addItem(temp[i]);
}
