please write this program by JAVA
Problem 2 (20 points) (Sum the digits in an integer) Write a method that computes the sum of the digits in an integer. Use the following method header: public static int sumbigits(long n ) For example, sumDigits (234) returns 9(=2+3+4). (Hint: Use the \% operator to extract digits and the / operator to remove the extracted digit. For instance, to extract 4 from 234 , use 234%10(=4 ). To remove 4 from 234 , use 234/10 (=23) ). Use a loop to repeatedly extract and remove the digit until all the digits are extracted. Write a test program that prompts the user to enter an integer then displays the sum of all its digits
