- 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 315I need some help with the analysisi of the following code: import java.util.*;public class Main { static void findSequence(int [] a, int l){ int x=1; int BNumber=a[0]; int y=0; int index=0; for(int n=1;n<l;n++){ if(a[n]!=a[n-1]){ if(x>y){ BNumber=a[n-1]; y=x; } x=1; }else { x++; } } if( x>y){ BNumber=a[l-1]; y=x; } index=y-1; System.out.println("The longest same number sequence starts at index "+index+" with "+y+" values of "+BNumber); } public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.print("Enter a series of numbers ending with 0: "); String s=sc.nextLine(); String[] splitArr = s.split(" "); int[] array = new int[splitArr.length]; for (int i = 0; i <…First, write a Java method isSequence that takes as parameters a non-empty 2-dimensional array of integers.
