I've returned with more Java help
I'm validating a first name entered into a the java.swing GUI textbox. It must start with Uppercase, follow Lowercase, and no numbers. For some reason one if statement is being ignored for displaying the error messagebox.
Code:
jtext1.addActionListener (
new ActionListener() {
public void actionPerformed(ActionEvent e) {
string1=jtext1.getText();
if(!string1.substring(0,1).matches("[A-Z]")){
errorReport+=errorUpper;
errorDetect=true;
}
if(!string1.substring(1,string1.length()).matches("[a-z]*")){
errorReport+=errorLower;
errorDetect=true;
}
for (i=0; i<string1.length(); i++){
if (Character.isDigit(string1.charAt(i))) {
errorReport+=errorAlpha;
errorDetect=true;
break;
}
}
if (errorDetect=true){
JOptionPane.showMessageDialog(null, errorReport);
}
errorDetect=false;
errorReport="Error: ";
jtext2.requestFocus();
}
}
);
Thank you for wasting your time to help me ^_^ |
