    Default Help with keeping the gui one size

    i have my little program here and it all works and everything but i would like the GUI to stay this size i have it set. Right now when you run it and you drag a corner it changes the whole look of the GUI and moves everything around. I was wondering if there is a way to keep it the size i have it now without it being able to change?

    package wlodmgcalc;
     
    import javax.swing.*;
    import java.awt.*;
    import java.awt.event.*;
     
    public class wlocalc extends JFrame  implements ActionListener {
    	static final long serialVersionUID = 0L;
     
    	JTextField atk;
    	JComboBox elementBox;
    	JButton calculate;
    	JLabel damageTotal;
    	JLabel warning;
    	String[] elements;
    	int cbox;
    	String atkNum;
     
    	public wlocalc() {
    		super("WLO Damage Calculator");
    		setSize(180, 230);
    		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		FlowLayout flow = new FlowLayout(FlowLayout.LEFT);
    		setLayout(flow);
     
    		JPanel row1 = new JPanel();
            JLabel atkLabel = new JLabel("Atk/Matk:");
    		row1.add(atkLabel);
    		atk = new JTextField(7);
    		row1.add(atk);
    		add(row1);
     
    		JPanel row2 = new JPanel();
    		JLabel elementLabel = new JLabel("Element:");
    		row2.add(elementLabel);
    		String[] elements = { "Wind", "Fire", "Water", "Earth" };
    		elementBox = new JComboBox(elements);
    		elementBox.addActionListener(this);
    		row2.add(elementBox);
    		add(row2);
     
    		JPanel row3 = new JPanel();
    		FlowLayout flowbutton = new FlowLayout(FlowLayout.CENTER, 50, 10);
    		row3.setLayout(flowbutton);
    		calculate = new JButton("Calculate");
    		calculate.addActionListener(this);
    		row3.add(calculate);
    		add(row3);
     
    		JPanel row4 = new JPanel();
    		JLabel totalLabel = new JLabel("Damage: ");
    		row4.add(totalLabel);
    		add(row4);
     
    		JPanel row5 = new JPanel();
    		damageTotal = new JLabel(atkNum);
    		row5.add(damageTotal);
    		add(row5);
     
    		JPanel row6 = new JPanel();
    		warning = new JLabel("Damage is to weak element");
    		row6.add(warning);
    		add(row6);
     
    		setVisible(true);
    	}
     
    	public void actionPerformed(ActionEvent event) {
    		String atknum = atk.getText();
    		int atkNumber = Integer.parseInt(atknum);
    		String element = (String)elementBox.getSelectedItem();
    		if (atkNumber == 0) {
    			damageTotal.setText("0");
    		} else if (element == "Wind") {
    			cbox = (int) ((atkNumber * 1.4 + 0 - 2 * 0.98) * 1.3);
    		} else if (element == "Fire") {
    			cbox = (int) ((atkNumber * 1.4 + 0 - 2 * 0.98) * 1.6);
    		} else if (element == "Water") {
    			cbox = (int) ((atkNumber * 1.4 + 0 - 2 * 0.98) * 1.4);
    		} else if (element == "Earth") {
    			cbox = (int) ((atkNumber * 1.4 + 0 - 2 * 0.98) * 1.3);
    		}
     
    		String pressed = event.getActionCommand();
    		if (pressed.equals("Calculate")) {
    			damageTotal.setText("" + cbox);
    		}
    		}
     
    	public static void main(String[] args) {
    		wlocalc dmg = new wlocalc();
    	}
    }

    Any and help is appreciated if you want to see how i mean just run that and maximize the window

    A comment on your code: } else if (element == "Wind") {
    Use the equals() method to compare the contents of Strings not the == operator
