WRITE A JAVA PROGRAM Methods can be used to define reusable code and organize and simplify code. Problem:- Suppose that you need to find the sum of integers from 5 to 15, from 16 to 30, and from 31 to 39, respectively. Define a public static sum method that take two int parameters -> (int start, int end) In the method, use for loop to add all the number from start to end. Later, invoke the sum inside the main method. Do the sum for each a) 5 to 15; b) 16 to 30; and c) 31 to 39 separately and later print the results. Output: Sum from 5 to 15 is 110 Sum from 16 to 30 is 345 Sum from 31 to 39 is 315

Write a java program that can examine school children on multiplication. The kid has to select which multiplication table he wants to be tested in.- Display 10 random questions every time,- Display whether the answers are right or wrong,- Show the correct answers for wrong answers and- calculate the total score (out of 10) ((((It is just AN EXERCISE NOT AN EXAM)))) Thanks
