Write the use of setEnabled() method in Java
Ans: The
code setEnabled(false), disables the TextField it is not selectable and user
can’t copy data from it and also user cannot able edit or copy ,it is just used
for preventing purpose from being edited,but it will still look the same as
TextFeild without setEnabled() method.
Draw the life Cycle of an Applet
1.
Develop a program using Label to display
message “Welcome to Java”
import java.awt.*;
class L
{
L()
{
Frame
f=new Frame();
Label
l1=new Label("Welcome to Java");
l1.setBounds(100,50,120,80);
f.add(l1);
f.setSize(500,500);
f.setLayout(null);
f.setVisible(true);
}
public static void main(String a[])
{
new
L();
}
}
Output:
2. Develop
a program to select multiple languages known to user.
import java.awt.*;
class Lan
{
Lan()
{
Frame f=new Frame();
Label l1=new Label("Select known Languages");
l1.setBounds(100,50,120,80);
f.add(l1);
Checkbox c1=new Checkbox("Marathi");
c1.setBounds(100,90,50,50);
f.add(c1);
Checkbox c2=new Checkbox("Hindi");
c2.setBounds(100,150,50,50);
f.add(c2);
Checkbox c3=new Checkbox("English");
c3.setBounds(100,200,80,50);
f.add(c3);
Checkbox c4=new Checkbox("Sanskrit");
c4.setBounds(100,250,80,50);
f.add(c4);
f.setSize(500,500);
f.setLayout(null);
f.setVisible(true);
}
public static void main(String
ar[])
{
new Lan();
}
}

f.add(b1);
Button b2=new
Button("Reset");
b2.setBounds(100,101,50,50);
f.add(b2);
Button b3=new
Button("Cancel");
b3.setBounds(100,150,80,50);
f.add(b3);
f.setSize(500,500);
f.setLayout(null);
f.setVisible(true);
}
public static void main(String a[])
{
new But();
}
}
