我是菜鸡，这种写法还有谁。。。。

public class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        float a = sc.nextFloat();
        String a1 = Float.toString(a);;
        String[] s = a1.split("\\.");
        char  c =  s[1].charAt(0);
        char[] d ={c};
        int e =Integer.parseInt(new String(d));
        if(e>=5){
            System.out.println((int)a + 1);
        }else{
             System.out.println((int)a );
        }
        
            
    }
}

}
