Clicking button to reverse text

[gary davis]

I want to create a button, so when it is clicked the text
in the JText area will be reversed.
public void actionPerformed(ActionEvent e)
{
if (actionCommand.equals("Reverse"))
else
theText.setText("Error in memo interfact.");
}

ok...here is what I would do...

String reverseText = "";
String originalText = "The Text you want to reverse";
int stringLength = originalText.length();
while(stringLength > 0)
{
     reverseText = reverseText + originalText.charAt(stringLength);
     stringLength--;
}

Let me know how this works for you!!

Here is my approach to it:

  
public void actionPerformed(ActionEvent e)
{
  if (actionCommand.equals("Reverse")) {
    StringBuffer sb = new StringBuffer(theText.getText());
    theText.setText( sb.reverse().toString() );
  } else {
    theText.setText("Error in memo interfact.");
  }
}

Regards,
Manfred.

You are correct, when I ran the program it does reverse the text.
Thanks to everyone.
