Part 1
A regular triangle is one for which all sides are congruent and all interior angles.
Create a class RegularTriangle with a field side (int)
Create a constructor which accepts an int parameter and will assign the parameter to field side
Create assessor and mutator for this class
Create a method getPerimeter() which should return 3*side;
Part 2
in the constructor, add a logic that if the input parameter is less than 5 then set the side to 5, if it is >10 then set the side to 10, otherwise set the side to the input value.
Screenshot final output
There are 12 inches in a foot and 3 feet in a yard.
Create a class named InchConversion. Its main() method accepts a value in inches from a user at the keyboard, and in turn passes the entered value to two methods. One converts the value from inches to feet, and the other converts the same value from inches to yards.
Each method displays the results with appropriate explanation.
import java.util.Scanner;
public class InchConversion {
public static void main (String args[]) {
// Write your code here
}
public static void convertToFeet(int inches) {
// Write your code here
}
public static void convertToYards(int inches) {
// Write your code here
}
}

The format of this line differs depending on the shape ( files supplied to me : ExampleShapes.txt, TwoRedCircles.txt, and ExampleShapesStill.txt) step 2 : I would start by trying to read a single line of the filefollowed by multiple lines, printing them to the screento ensure you are reading the data correctly. Then, cre-ate instances of the shape objects and print them out.You can do this by calling the toString() methodthat has already been given to you. step 3: If the file does not exist, quit the program grace-fully and output Could not find <filename>to the screen (standard out) with <filename> re-placed by the file that will not open.

A TimeSpan object stores a span of time in hours and minutes (for example, the time span between Monday 8AM and Wednesday 10:30AM is 50 hours, 30 minutes). Each TimeSpan object should have the following public methods: 00000 TimeSpan (hours, minutes) Constructs a Timespan object storing the given time span of minutes and seconds. add (hours, minutes) Adds the given amount of time to the current time span (e.g. 2 hours, 15 min + 1 hour, 45 min = 4 hours). Assume that the arguments are valid: the hours are non-negative, and the minutes are between 0 and 59. add (timespan) Adds the given amount of time (stored as a time span) to the current time span. getTotalHours () Returns the total time in this time span as the real number of hours (such as 9.75 for 9 hours, 45 min). tostring () Returns a string representation of the time span of hours and minutes, such as "28h4 6m". The minutes should always be reported as being in the range of 0 to 59.

This is called by the driver and should handle all of the input from the Scanner and dialog for the user. isValid: returns true or false if a given String has the correct date and time. The String parameter should be formatted “MM/DD hh:mm” This method should call the methods isValidDate and isValidTime to determine this. isValidDate: returns…arrow_forward
