- Write a void method which will print out a sentence “Hello World!”. Call the method from main().Java: The class will contain the following static methods: reverseS – A method that displays a string reversely on the console using the following signature: public static void reverseS(String s) printSub1 – print all substrings of a string (duplicated substrings are allowed, but loops are not allowed). The method signature: public static void printSub1(String s) printSub2 – print all substrings of a string (duplicated substrings are not allowed, but loops are allowed). The method signature: public static void printSub2(String s) Note: All methods should be RECURSIVE. Any predefined classes that are based on Set are not allowed. Allow the user to input the string! In the main method, read a string from the user and output the reversed string and substrings to the screen: Sample Run: Please input a string: abcd The reversed string: dcba The substrings of the input string: abcd abc ab a b bc b c bcd bc b c cd c d The substrings of the input string: a ab abc…JAVA HELP PLEASE! Write a class Rectangle that has only the following public methods (you can add other non-public methods if you think you need them): Write a constructor that creates a rectangle using the x, y coordinates of its lower left corner, its width and its height (the parameters must be in that order). Creating a rectangle with non-positive width or height should not be allowed; throw an IllegalArgumentException for those cases. The values of x and y are allowed to be negative. Write a method overlap(Rectangle other). This method should return true if this rectangle overlaps with other, false otherwise. Rectangles that touch each other are not considered to be overlapping. Write a method toString that returns a String. The string should be formatted exactly as:“x:2, y:3, w:4, h:5”without the quotation marks and replacing the numbers with the actual attribute values of the object. A class called Rectangle exists in Java already. You are not allowed to use this class in any…

Complete method printPopcornTime(), with int parameter bagOunces, and void return type. If bagOunces is less than 2, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bagOunces followed by " seconds". End with a newline. Example output for ounces = 7: 42 seconds import java.util.Scanner; public class PopcornTimer {public static void printPopcornTime(int bagOunces) { /* Your solution goes here */ } public static void main (String [] args) {Scanner scnr = new Scanner(System.in);int userOunces; userOunces = scnr.nextInt();printPopcornTime(userOunces);}} .Analyze the following code. public class Test { public static void main(String[] args){ System.out.printlin( m(2) ); public static int m( int num ) { return num; } public static void m( int num ) { System.out.printin( num ); } The program has a compile error because the second m method is def method.

The while loop repeats a set of code while a condition is not met. The number of iterations required of a while loop is always known before the while loop begins. The while loop repeats a set of code while a condition is met. The while loop does not require code to be added to manage iteration during each loop. Which of the following statements is true with regard to java exceptions? A try block can be followed by multiple catch blocks. A program automatically terminates immediately after a catch block is executed. Only one try/catch block is allowed in a single method. A try-catch is required in all methods.Design a program using Java NetBeans (Console application).
