- Write a Java method that Let (rx1,ry1) and (rx2, ry2) be the top left and bottom right corners of a rectangle, and (px1,py) and (px2,py) the two end points of a horizontal line segment. Determine if the line segment lies completely inside the rectangle, lies completely outside the rectangle, or overlaps the rectangleWhat will be the output of the following Java program? class Output { public static void main(String args[]) { Double i = new Double(257.5); Double x = i.MAX_VALUE; System.out.print(x); } }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

A palindrome is a word, phrase, or sentence that reads left-to-right the same way it reads right-to-left, ignoring all punctuation and capitalization. For example, the statement “Madam, I’m Adam” is a palindrome as the response of “Eve.” Use a method to determine if a String is a palindrome. Test a single word non-palindrome, a single word palindrome, a phrase that is not a palindrome, and a phrase that is a palindrome. Print the phrase and whether it is a palindrome or not. Some simple palindromes are “racecar,” “taco cat,” and “A man, a plan, a canal, Panama!” There are a few different approaches for the test; choose one of your liking. Hint: extract all letters, change the remaining letters to lowercase, then test if the phrase is a palindrome.WRITE THE BODY OF Java program - THE checkWinner METHOD BELOW SO THAT THE GAME STOPS WHEN SOMEONE WINS, OR WHEN THE BOARD IS FULL.
