In this assignment you will demonstrate your knowledge of debugging by fixing the errors you find in the program below. Fix the code, and paste it in this document, along with the list of the problems you fixed.This example allows the user to display the string for the day of the week. For example, if the user passed the integer 1, the method will return the string Sunday. If the user passed the integer 2, the method will return Monday. This code has both syntax errors and logic errors. Hint: There are two logic errors to find and fix (in addition to the syntax errors).Inport daysAndDates.DaysOfWeek;public class TestDaysOfWeek {public static void main(String[] args) {System.out.println("Days Of week: ");for (int i = 0;i < 8;i++) {System.out.println("Number: " + i + "\tDay Of Week: " + DaysOfWeek.DayOfWeekStr(i) )}}}package daysAndDatespublic class DaysOfWeek {public static String DayOfWeekStr(int NumberOfDay) {String dayStr = ""switch (NumberOfDay) {case 1:dayStr =…

X609: Magic Date A magic date is one when written in the following format, the month times the date equals the year e.g. 6/10/60. Write code that figures out if a user entered date is a magic date. The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. Examples: magicDate(6, 10, 60) -> true magicDate(50, 12, 600) –> false
1. A method called convertFromDecimal which takes two integers as parameters. The first integer is the decimal number to be converted and the second integer is the base to be converted to. The base value could be any number between 2 (binary) and 16 (hexadecimal). The converted number is returned as a String. Hints: • Remember that in order to convert a decimal number that includes only an integer part to a base n, you need to use repeated integer division of successive quotients on n saving the remainder in each step until the quotient is zero. • Remember that numbering systems with bases 11-16 use letters in order to continue counting after the digit 9. For example, the numbering system with base 12 has the following digits: {0,1,2,3..9,A,B}. ...... 2. In your main method declare and initialize an integer. Then print its representation in all numbering systems from 2-16 by invoking the method convertFromDecimal. You should use a for loop for this part.
