Answer 1

Actually issue is with class name. FlowLayout is a class of java.awt package. you are trying to make a class with same name and still using the java.awt class. which is giving the issue.

So simple solution is to rename the class. Below is the correct code. Please include your imports.

/**

* Write a description of class FlowLayout here.

*

* @author (your name)

* @version (a version number or a date)

*/

public class MyFlowLayout {

// instance variables - replace the example below with your own

JButton button1, button2, button3;

JFrame jFrame;

/**

* Constructor for objects of class FlowLayout

*/

MyFlowLayout() {

// initialise instance variables

jFrame = new JFrame("FlowLayout Example");

jFrame.setLayout(new FlowLayout(FlowLayout.CENTER));

jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

button1 = new JButton("Left");

button2 = new JButton("Center");

button3 = new JButton("Right");

jFrame.add(button1);

jFrame.add(button2);

jFrame.add(button3);

jFrame.setSize(250, 80);

jFrame.setVisible(true);

}

/**

* An example of a method - replace this comment with your own

*

* @param y

* a sample parameter for a method

* @return the sum of x and y

*/

public static void main(String[] args) {

new MyFlowLayout();

}

}
