Increase font size in JButton

I do not understand what to do to complete my project. I am working on a Connect Four game and I would like to increase the font size inside JButton. I'm relatively new to programming, and I haven't worked with fonts yet. I just would like to at least double the font inside the button to make it more visible during the game. Can someone help me or point me to find a solution? Thank you My code is below.

import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Connect implements ActionListener { private JFrame window = new JFrame("Connect Four by Steven and Anthony"); private JPanel myPanel = new JPanel(); private JPanel myPanelB = new JPanel(); private JButton[][] myButtons = new JButton[6][7]; private JButton[] buttons = new JButton[7]; private boolean win = false; private int count = 5; private int count2 = 5; private int count3 = 5; private int count4 = 5; private int count5 = 5; private int count6 = 5; private int count7 = 5; private int countA = 0; private String letter = ""; public boolean checkHorizontalWin(String letter) { for (int y = 0; y < myButtons.length; y++) { for (int x = 0; x < myButtons[y].length - 3; x++) { if (myButtons[y][x].getText().equals(letter) && myButtons[y][x + 1].getText().equals(letter) && myButtons[y][x + 2].getText().equals(letter) && myButtons[y][x + 3].getText().equals(letter) ) { return true; } } } return false; } public boolean checkVerticalWin(String letter) { for (int y = 0; y < myButtons.length - 3; y++) { for (int x = 0; x < myButtons[y].length; x++) { if (myButtons[y][x].getText().equals(letter) && myButtons[y + 1][x].getText().equals(letter) && myButtons[y + 2][x].getText().equals(letter) && myButtons[y + 3][x].getText().equals(letter) ) { return true; } } } return false; } public boolean checkDiagonalToTheLeftWin(String letter) { for (int y = 0; y < myButtons.length - 3; y++) { for (int x = 0; x < myButtons[y].length - 3; x++) { if (myButtons[y][x].getText().equals(letter) && myButtons[y + 1][x + 1].getText().equals(letter) && myButtons[y + 2][x + 2].getText().equals(letter) && myButtons[y + 3][x + 3].getText().equals(letter) ) { return true; } } } return false; } public boolean checkDiagonalToTheRightWin(String letter) { for (int y = 0; y < myButtons.length - 3; y++) { for (int x = 3; x < myButtons[y].length; x++) { if (myButtons[y][x].getText().equals(letter) && myButtons[y + 1][x - 1].getText().equals(letter) && myButtons[y + 2][x - 2].getText().equals(letter) && myButtons[y + 3][x - 3].getText().equals(letter) ) { return true; } } } return false; } public Connect(){ window.setSize(800,700); window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); myPanel.setLayout(new GridLayout(1,7)); myPanelB.setLayout(new GridLayout(6,7)); for (int i = 0; i < buttons.length; i ++){ buttons[i] = new JButton(); myPanel.add(buttons[i]); buttons[i].addActionListener(this); } for (int i = 0; i < 6; i ++){ for (int j = 0; j < 7; j ++){ myButtons[i][j] = new JButton(); myPanelB.add(myButtons[i][j]); } } window.add(myPanel, BorderLayout.NORTH); window.add(myPanelB, BorderLayout.CENTER); window.setVisible(true); } public void actionPerformed(ActionEvent e){ countA++; if (countA % 2 == 0) letter = "X"; else letter = "O"; if (e.getSource() == buttons[0]){ myButtons[count][0].setText(letter); count --; } if (e.getSource() == buttons[1]){ myButtons[count2][1].setText(letter); count2 --; } if (e.getSource() == buttons[2]){ myButtons[count3][2].setText(letter); count3--; } if (e.getSource() == buttons[3]){ myButtons[count4][3].setText(letter); count4--; } if (e.getSource() == buttons[4]){ myButtons[count5][4].setText(letter); count5--; } if (e.getSource() == buttons[5]){ myButtons[count6][5].setText(letter); count6--; } if (e.getSource() == buttons[6]){ myButtons[count7][6].setText(letter); count7--; } if (myButtons[0][0].getText().equals("O") || myButtons[0][0].getText().equals("X")){ buttons[0].setEnabled(false); } if (myButtons[0][1].getText().equals("O") || myButtons[0][1].getText().equals("X")){ buttons[1].setEnabled(false); } if (myButtons[0][2].getText().equals("O") || myButtons[0][2].getText().equals("X")){ buttons[2].setEnabled(false); } if (myButtons[0][3].getText().equals("O") || myButtons[0][3].getText().equals("X")){ buttons[3].setEnabled(false); } if (myButtons[0][4].getText().equals("O") || myButtons[0][4].getText().equals("X")){ buttons[4].setEnabled(false); } if (myButtons[0][5].getText().equals("O") || myButtons[0][5].getText().equals("X")){ buttons[5].setEnabled(false); } if (myButtons[0][6].getText().equals("O") || myButtons[0][6].getText().equals("X")){ buttons[6].setEnabled(false); } if (checkHorizontalWin(letter) || checkVerticalWin(letter) || checkDiagonalToTheLeftWin(letter) || checkDiagonalToTheRightWin(letter) ) { win = true; if (win == true) { JOptionPane.showMessageDialog(null, letter + " has won!"); System.exit(0); } } } /** * * @param args */ public static void main(String[] args){ new Connect(); } }

You can use:

 button.setFont(new Font("Arial", Font.PLAIN, 40));
  • "Arial" is obviously the name of the font used.
  • Font.PLAIN means plain text (as opposed to bold or italic).
  • 40 - font size (using the same numbering system for font size as Microsoft Word)

I'm not sure if this will work, but looking at the JButton docs, there is setFont (font font) that you can call. You can try passing the Font created using the font size you want to use with the Font(String name, int style, int size) constructor Font(String name, int style, int size) .

It works great with setFont(Font) . But there is only one problem, it also affects the size of your button if the font size is large enough ...
