Question

Q: Create a version of the UnitConverter application to convert from inches to foot. Read the inches value from the user.

A:

import java.util.*;
class UnitConverter{
   public static void main(String[] args){
int inches;
int foot;

Scanner scan=new Scanner(System.in);
System.out.println("Enter inches:");
inches=scan.nextInt();
System.out.println(inches/12+" feet and "+inches%12+" inches.");
}
}

Q: Write a program that converts grams to pounds. (One pound equals 453.592 grams.) Read the grams value from the user as a floating point value.

A:

import java.util.*;
class GramsToPounds{
   public static void main(String[] args){
double pounds;
double grams;
Scanner scan=new Scanner(System.in);
System.out.println("Enter grams:");
grams=scan.nextFloat();
pounds=grams/453.592;
System.out.println(pounds+" pounds");
}
}

Q: Write a program that reads values representing the weight in kilograms, grams, and milligrams and then prints the equivalent weight in milligrams. (For example, 1 kilogram, 50 grams, and 42 milligrams is equivalent to 10,50,042 milligrams.)

A:

import java.util.*;
class ProblemMilligrams{
public static void main(String[] args){
int kilograms;
int grams;
int milligrams;
int millik;
int millig;
Scanner scan=new Scanner(System.in);
System.out.println("Enter kilograms:");
kilograms=scan.nextInt();
System.out.println("Enter grams:");
grams=scan.nextInt();
System.out.println("Enter milligrams:");
milligrams=scan.nextInt();
millik=kilograms*1000000;
millig=grams*1000;
System.out.println((millik+millig+milligrams)+" milligrams");
}
}

Q: Create a version of the previous project that reverses the com- putation. That is, read a value representing the weight in mil- ligrams, then print the equivalent weight as a combination of kilograms, grams, and milligrams. (For example, 90,70,056 milligrams is equivalent to 9 kilograms, 70 grams, and 56 milligrams.)

A:

import java.util.*;
class ProblemMilligramsBackwards{
public static void main(String[] args){
int kilograms;
int grams;
int milligrams;

Scanner scan=new Scanner(System.in);

System.out.println("Enter milligrams:");
milligrams=scan.nextInt();
kilograms=milligrams/1000000;
milligrams=milligrams%100000;
grams=milligrams/1000;
milligrams=milligrams%1000;
System.out.println(kilograms+" kilograms, "+grams+" grams, "+milligrams+" milligrams.");
}
}

These are the questions and answers but I can't understand how to put it into one java file, I need help with putting all these codes into one file.

Answer 1

import java.util.*;

class UnitConverter {

public static void main(String[] args) {

int inches;

int foot;

Scanner scan = new Scanner(System.in);

System.out.println("Enter inches:");

inches = scan.nextInt();

System.out.println(inches / 12 + " feet and " + inches % 12 + " inches.");

double pounds;

double grams;

scan = new Scanner(System.in);

System.out.println("Enter grams:");

grams = scan.nextFloat();

pounds = grams / 453.592;

System.out.println(pounds + " pounds");

int kilograms;

int milligrams;

int millik;

int millig;

scan = new Scanner(System.in);

System.out.println("Enter kilograms:");

kilograms = scan.nextInt();

System.out.println("Enter grams:");

grams = scan.nextInt();

System.out.println("Enter milligrams:");

milligrams = scan.nextInt();

millik = kilograms * 1000000;

millig = (int) (grams * 1000);

System.out.println((millik + millig + milligrams) + " milligrams");

scan = new Scanner(System.in);

System.out.println("Enter milligrams:");

milligrams = scan.nextInt();

kilograms = milligrams / 1000000;

milligrams = milligrams % 100000;

grams = milligrams / 1000;

milligrams = milligrams % 1000;

System.out.println(kilograms + " kilograms, " + grams + " grams, " + milligrams + " milligrams.");

}

}
