How can I declare two variable?

Oct 29th, 2009

I'm too new in java and I always appreciated when you share with me your knowledge. Here I'm trying following self-test exercise;

Give two declaration for two variables called feet and inches.Both variables are of type int and both are to be initialised to zero in declaration.
I try this way and it's compilable !! but not sure....did I miss something?

public class feetInches
{
public static void main(String [] args)
{
int feet = 0;
int inches = 0;
int totalFeet = inches * 12;

System.out.println("5 feet is " + 5* 12);

}

}
Thank you in advance

Sorry for the double posting but a better way would be:

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
public class feetInches
{
public static final int FEET_TO_INCHES = 12;
public static final double INCHES_TO_FEET = 1.0/12.0;
 
public static void main(String [] args)
{
int feet = 5;
int inches = feet * FEET_TO_INCHES ;
 
System.out.println(feet + " feet is " + inches);
}
}
public class feetInches
{
public static final int FEET_TO_INCHES = 12;
public static final double INCHES_TO_FEET = 1.0/12.0;

public static void main(String [] args)
{
int feet = 5;
int inches = feet * FEET_TO_INCHES ;

System.out.println(feet + " feet is " + inches);
}
}

would you mind also to help me this:

Write Java assignment statement that will set the value of the variable distance to value of the time multiplied by 80. All the variable are of type int.

public class timetoDistance

{

public static void main(String [] args)

{

int time;
Int distance;

}

}

???
Thank you in advance

It's not that difficult. Multiply time by 80 and put it in the distance

JavaAddict,
sorry, to disturb you again. How can I build without having rate? e.g.

rt=d (rate multiplied by time = distance)

Thank you in advance

Your question doesn't make sense.

int distance = 80 * time;
// or
int rate = 80;
int time = ...;
int distance = rate * time;

int rate = 80;
int time = ...;
int distance = rate * time;
