Day 2: In 16
May, 2019 we have implemented the functionalities to the Frame created on 15th
May,2019. We implemented functionality like to move from one frame another
frame. Login Credential validation, Enabling the exit button, Changing the text
color of label on Click Event and Signing Up the User.
Work
Done:
11) Moving the Frame to another Frame: For this we have used the setVisible() method
to visible the form and hide current form.
2 2) Login Credential Check: For this we have created function checkCredential() method to check
login id and password.
void checkCredential() {
try {
String uname = txtUname.getText();
String upwd = new
String(txtPwd.getPassword());
//JOptionPane.showMessageDialog(this,uname);
// To Check Credentials
if (uname.equals("User")
&& upwd.equals("Pass1")) {
lblstatus.setText(" Login
Success ");
} else {
lblstatus.setText("
Invalid Credentails ");
}
} catch (Exception e) {
e.printStackTrace();
}
}
3) For changing color on clicking the Label: For this we have used MouseClick Event of
java.awt.event package. Then we set the foreground color of the label using
setForeground(Color) in-built method of java.awt.Color class.
4) For Exit: To
exit we have used System.exit(0) method.
5) For Sign-Up:
In this we have implemented that if there is blank in TextField then it will
not accept the Submit and if all fields are filled then Submit Button will
directly Move into Login Frame.
Follow Standards: Use Variable with same starting
ex: 1) Button: btn
2) TextField: txt
3) Lable: lbl
To do Auto Indentation Use: Alt + Shift + f
To go to the function: Ctrl
To get Function: Ctrl +
Space
To import : Alt+Shift+i
To show Popup: JOptionPane.showMessageDialog(this,”Message”);
