java控制台输入一个正整数，判断它是否为质数

public static void main(String[] args) {
    Scanner scanner=new Scanner(System.in);
    System.out.print("请输入您要检测是否为质数的数:");
    long number=scanner.nextLong();
    long i;

    for(i=2; i<=number; i++){
        if(number%i==0){
            if(number==i){
                System.out.println(number+"是质数");
                break;
            }
            else{
                System.out.println(number+"不是质数");
                break;
            }
        }
    }
}
