I am at a loss of what to do for the finalization of my term project. I am working on a Connect Four game and I'd like to increase the font size inside of a JButton. I'm relatively new to programming and I haven't worked anything with fonts yet. I'd just like to at least double the font inside of the button to make it more visible during gameplay. Can someone help me, or point me into the direction of finding a solution? Thanks! My code is below.

推荐答案
您可以使用:
button.setFont(new Font("Arial", Font.PLAIN, 40));
-
"Arial"显然是所使用字体的名称. -
Font.PLAIN表示纯文本(与粗体或斜体相对). -
40是字体大小(对字体大小使用与Microsoft Word相同的编号系统) "Arial"is obviously the name of the font being used.Font.PLAINmeans plain text (as opposed to bold or italic).40is the font size (using the same numbering system for font size as Microsoft Word)
