Thread: 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") {

		} 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
