Question

I am attempting to add a button to my JFrame.
I am unable to assign the JButton to a certain size.

I have tried

mJButtonOne.setPreferredSize
mjButtonOne.setMinimum/maximum
mjBUttonOne.setSize

No matter what I try the button always loads full screen.

Here is my code I am using a few methods, a make, a build, and a dostuff.

private void make() {
    this.mJLabelTime = new JLabel("");
    this.mJButtonOne = new JButton("");
//I have tried setting size in do stuff as well.

      }

private void build(){
    this.add(this.mJLabelTime);
    this.add(this.mJButtonOne);

     }

private void doStuff(){

    this.mJLabelTime.setText(Customtime.time("HH:mm:ss"));
    this.mJButtonOne.setText("BUTTON!");
    this.mJButtonOne.setPreferredSize(new Dimension(1, 10));

My Main looks like this.

public static void main(String[] args) {
    View view = new View();
       view.setMaximumSize(new Dimension(200, 200));
       view.setMinimumSize(new Dimension(200, 200));
    view.setVisible(true);
System.out.println("Running app..."); 
//System.out.println("Goodbye World");    
}

If you are not using any LayoutManager, call setLayout(null) for your View class.

But it’s recommended that you pick and use a layout manager and let the layoutmanager take care of sizing components.
