Task #1 Correcting Logic Errors in Formulas In this task you will use an existing Java program and correct several logic errors 1. Download the file NumericTypes.java from Blackboard. 2. Compile the source file, run the program, and observe the output. Some of the output is incorrect You need to correct logic errors in the average formula and the temperatureo or formula problems. The necessary formulas are

If you have any doubts, please give me comment...

Task1:

public class NumericTypes{

public static void main(String[] args) {

int score1 = 95;

int score2 = 100;

int numberOfScores = 2;

double average = (double)(score1+score2)/numberOfScores;

System.out.println(score1 + " and " + score2 + " have an average of " + average);

double F = 212;

double C = (5/9.0)*(F-32);

System.out.println(F + " in Fahrenheit is " + C + " in Celsius.");

}

}

Task 2:

import java.util.Scanner;

/**

* Task #1 before adding Task#2 where indicated.

public class NumericTypesOriginal {

public static void main(String[] args) {
