Java编程求一个四位整数的逆序数加1，例如输入：1234，输出4322

Java编程求一个四位整数的逆序数加1，例如输入：1234，输出4322

截取字符串、 倒叙塞入数组、拼接字符串、转成整数、最后+1

int a = 1234;
        int b = 0;
        while (a>0){
            b = b*10+a%10;
            a /= 10;
        }
        System.out.println(b+1);

    public static void main(String[] args) {
        System.out.println("输入一个四位整数:");
        Scanner sc=new Scanner(System.in);
        int next=sc.nextInt();
        int qian=next/1000;
        int bai=next/100%10;
        int shi=next/10%10;
        int ge=next%10;
        int result=(ge*1000)+(shi*100)+(bai*10)+(qian+1);
        System.out.println("result:"+result);
    }
