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, ...
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...
方法:public static int sumDigits(long n)例如:sumDigits(234)返回9(2+3+4)要求:使用求余算运算符%提取数字,用除号/去掉提取出来的数字.例如:使用234%10(=4)抽取4,然后使用234/10从234中去掉4.使用一个循环来反复提取和去掉每位数字,直到所有的数都提取完为止....
total=total+remdr; number=number/10; } System.out.print("Sum of digits of number "+tempNum+" is "+total); } } Output: Enter a Number : 5385 Sum of digits of number 5385 is 21 That’s all about Java program to add digits of number....
public int[] plusOne(int[] digits) { // write your code here int extra = 1; for (int i = digits.length - 1; i >= 0; i--) { int sum = digits[i] + extra; //保留一位数。 digits[i] = sum % 10; //若出现进位,则保留进位。
System.out.print(*Enteranintegerbetween0and1000:); intnumber=input.nextlnt(); //Findalldigitsinnumber intlastDigit=number%10; intremainingNumber=number/10; intsecondLastDigit=remainingNumber%10; remainingNumber=remainingNumber/10; intthirdLastDigit=remainingNumber%10; ...
不完全确定这是不是你想要的东西。它确实简化了您的代码，并根据剩余部分构建数组：
Given a number, we have to find the sum of digits using the recursion.Submitted by Nidhi, on June 02, 2022 Problem statementIn this program, we will read an integer number from the user and then we will calculate the sum of the digits of the input number using recursion....
The number of baskets and the number of apples in each basket are integer values. int total = baskets * applesInBasket; Multiplying those values we get an integer, too. $ java Main.java There are total of 384 apples Integers can be specified in four different notations in Java: decimal...
