Finally, it returns the 'sum' containing the sum of the digits. Finally, back in the "main()" method, it prints the result of the "sumDigits()" method, displaying the sum of the digits of the entered integer. Sample Output: Input an intger: 25 The sum of the digits is: 7 Flowch...
return sum;}public static void main(String[] args) {try{System.out.println("请输入数字:");Scanner sc=new Scanner(System.in);long l=sc.nextLong();System.out.println("输入数字的各位数之和为"+sumDigits(l));}catch(Exception e){System.out.println("您输入的不是数字!");}}}运行结果:请...
how to find the sum of digits of an integer number in Java. In thefirst part, we have solved this problem without using recursion i.e. by using a while loop and in this part, we will solve it by using recursion. It's good to know different approaches to solving the same problem, ...
Algorithm for Java Sum of Digits : step 1: Set sum=0 step 2: Read num step 3: Repeat through step-5 while num greater than 0 step 4: temp=num % 10 step 5: sum=sum+temp
拿Integer举例,其他的类似。转换方法如下: 格式化数字打印输出: 之前你看到过print和println的方法打印字符串作为System.out的标准输出。 因为所有的数值都可以被转换成字符串,你可以使用这些方法输出一个任意混合的字符串和数值。不止如此, Java程序语言还有一些其他方法允许你执行更多的输出控制。 比如java.io包中的Pr...

Reverse digits of an integer. Example1: x = 123, return 321 Example2: x = -123, return -321 解题思路:将数字翻转并不难,可以转成String类型翻转,也可以逐位翻转,本题涉及到的主要是边界和溢出问题,使用Long或者BigInteger即可解决。 题目不难: JAVA实现如下: public class Solution { static public ...
