Need help in java program, please?

Question

So,I get a homework of java program from school.Total 4 program and I have done 2 but I can understand the remaining two programs.
Remember all program should be done using Scanner Class.

1.Write a java program to input the temperature in degree Celsius and find in degree Fahrenheit (Using Scanner Class).

2.Write a java program to find if the number of days is 67,then it is equivalent to how many months and days,assuming the no. of days in a month is 30 (Using Scanner Class and without input).

Thanks in advance.

Answer 1

Here's a solution to question 2:



import java.util.Scanner;



public class MonthsAndDays {



public static void main(String[] args) {



final int DAYS_IN_MONTH = 30;



int months = 0, days = 0;



Scanner scan = new Scanner(System.in);



System.out.print("Enter number of days: ");

days = scan.nextInt();



months = days / DAYS_IN_MONTH;

days %= DAYS_IN_MONTH;



System.out.print(months + " month");

System.out.print(months==1? ", ": "s, "); // singular or plural

System.out.print(days+" day");

System.out.print(days==1? ".": "s."); // singular or plural



}//end main()

}//end class

Answer 2

Why roll your own when there is in all likelihood a calendar widget you can reuse? By the way, the Java API itself provides many useful classes and interfaces: Date, Calendar, GregorianCalendar, DateFormat, and SimpleDateFormat.

Answer 3

solution for question 1

---------------------------------------





import java.util.Scanner;



public class CF {



public static void main(String args[]) {

Scanner input = new Scanner(System.in);

System.out.println("Enter the temperature in Celsius: ");

double c = input.nextDouble();

System.out.println(c + " celsius = " + ((c * 9.0 / 5.0) + 32) + " fahrenheit.");

}

}

Well he sure is learning from those just writing his code.

Not a good practice. he isn't learning a thing and you aren't there for test.

Answer 5

Change Your Question from "Need help in java program, please?" to "see the objectives for my program and write it for me"
