在java代码中写对话框的显示 便于在action未执行完时与前台交互

//设置对话框样式
UIManager.put("OptionPane.background", Color.decode("#CCD8E7"));
UIManager.put("Panel.background", Color.decode("#CCD8E7"));
UIManager.put("Panel.font", new FontUIResource(new Font("微软雅黑", Font.PLAIN, 14)));
UIManager.put("Button.background", Color.decode("#F3F3F3"));
UIManager.put("Button.font", new FontUIResource(new Font("微软雅黑", Font.PLAIN, 12)));
//显示对话框
int a = JOptionPane.showConfirmDialog(
null, "'"+name+"'小区已存在是否覆盖","提示",JOptionPane.YES_NO_CANCEL_OPTION
);
//a = 1点击否 a=0点击是
if(a == 1){ .....}else if(a == 0){........}
