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 startint 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

// Define a sum method with two int parameters, 'start' and 'end'
6
// Inside the sum Method bracket, the summation must be done using
7
// for loop from 'start' to 'end', and then return the result
