我想知道如何在这个老虎机代码中显示jPanel5中的文本。这是我的代码
jButton1.setActionCo package slotmachine2;

return roll;
}
public int getSlot2(){
Random r = new Random();
roll2 = r.nextInt(6)+1;
return roll2;
}
public int getSlot3(){
Random r = new Random();
roll3 = r.nextInt(6)+1;

我忘记了如何在标签上添加文字，我想把文字分配给jLabel5，这样每次滚动时，我的初始编号（我的理想编号为30）会下降1.我知道我可以做金钱 - ;但我不知道如何每次都显示新号码。此外，我已经在互联网上寻求任何帮助，但遗憾的是我无法找到有关此主题的任何信息。提前谢谢！
答案 0 :(得分：0)
您应该只设置如下文字：
jLabel5.setText("newDesiredText");
