CODE:

import java.util.Scanner;

public class Weight {
public static void main(String args[]){
   Scanner in=new Scanner(System.in);

   int choice;
   float weight;
   do{
       System.out.print("Menu for conversion of your weights ");
       System.out.print("1>To calculate your weight on Earth's Moon ");
       System.out.print("2>To calculate your weight on Mars ");
       System.out.print("3>To calculate your weight on Venus ");
       System.out.print("4>To calculate your weight on Mercury ");
       System.out.print("5>Exit ");
       System.out.print("Enter your choice ");
       choice=in.nextInt();
       switch(choice){
       case 1:
System.out.print(" Enter your weight on earth ");
weight=in.nextInt();
System.out.print("Your weight on Earths moon is "+ Weight.moonWeight(weight)+" ");
break;
       case 2:
System.out.print(" Enter your weight on earth ");
weight=in.nextInt();
System.out.print("Your weight on Mars is "+ Weight.marsWeight(weight)+" ");
break;
       case 3:
System.out.print(" Enter your weight on earth ");
weight=in.nextInt();
System.out.print("Your weight on Venus is "+ Weight.venusWeight(weight)+" ");
break;
       case 4:
System.out.print(" Enter your weight on earth ");
weight=in.nextInt();
System.out.print("Your weight on Mercury is "+ Weight.mercuryWeight(weight)+" ");
break;

       case 5:
           return;

       }
   }while(choice!=5);


}
public static float moonWeight(float weight){
   float mweight=weight/6;
   return mweight;
}
public static float marsWeight(float weight){
   float mweight=(float) ((weight/9.81)*3.711);
   return mweight;
}
public static float venusWeight(float weight){
   float mweight=(float) ((weight/9.81)*8.87);
   return mweight;
}
public static float mercuryWeight(float weight){
   float mweight=(float) ((weight/9.81)*3.7);
   return mweight;
}
}
