3. List (int row-num, Boolean multipleMode)

9] Button

A button is basically a control component with a label that generates an event when pushed.

    Checkbox chk4 = new Checkbox("2nd", chk_obj, false);

    chk4.setBounds(250, 180, 50, 30);

    f1.add(chk4);

    Checkbox chk5 = new Checkbox("3rd", chk_obj, false);

    chk5.setBounds(300, 180, 50, 30);

    f1.add(chk5);

    // Choice

    Label lb5 = new Label("Languages :");

    lb5.setBounds(50,230,70,30); 

    f1.add(lb5);

    Choice c1 = new Choice();

    c1.setBounds(200, 230, 80, 40);

    c1.add("Java");

    c1.add("C");

    c1.add("C++");

    c1.add("PHP");

    c1.add("Python");

    f1.add(c1);

    // List

    Label lb6 = new Label("Branch :");

    lb6.setBounds(50,270,70,30); 

    f1.add(lb6);

    List ls1, ls2;

    ls1 = new List();

    ls1.setBounds(200, 270, 120, 50);

    ls1.add("Info. Tech.");

    ls1.add("Computer");

    ls1.add("Mechanical");   

    ls1.add("Meta");

    f1.add(ls1);

    Label lb7 = new Label("Education :");

    lb7.setBounds(50,340,70,32); 

    f1.add(lb7);

    ls2 = new List();

    ls2.setBounds(200, 340, 120, 20);

    ls2.add("Engineering");

    ls2.add("Polytechnic");

    f1.add(ls2);

    // Button

    Button b1=new Button("Submit"); 

    b1.setBounds(140,390,50,30);  //(x-coordinate -, y-coordinate |, width, height)

    f1.add(b1);  

    f1.setSize(1000,600);    // (width , height)  

    f1.setLayout(null);  

    f1.setVisible(true);   

}  

}
