hello

hi guys i'm new to java .
can you guys help me with this?
+4'7''
+3'10''
+6'4''
its gone be calculete sum with feet and inches and out come has to be
14 feet9inches

This is a simple problem with many possible solutions. I have done it in a very simple way. I first developed the following class.

Code:

---

public class Length {
        private int _feet;
        private int _inches;
       
        public Length(int f, int i)
        {
                this._feet = f;
                this._inches = i;
        }
       
        public void showLength()
        {
                System.out.println(_feet+"' "+_inches+"''");
        }
       
        public Length add(Length l)
        {
                int inches=l._inches+this._inches;
                int feet=l._feet+this._feet;
               
                if (inches>12)
                {
                        feet+=inches/12;
                        inches%=12;
                }
                return new Length(feet, inches);
        }
}

Then I wrote the following client class to do the addition for me.

Code:

---

public class LengthAdderClient {

        /**
        * @param args
        */
        public static void main(String[] args) {
                // TODO Auto-generated method stub
                Length l1=new Length(4,7);
                Length l2=new Length(3,10);
                Length l3=new Length(6, 4);
                Length sum=l1.add(l2);
                sum=sum.add(l3);
                System.out.print("Length 1: ");
                l1.showLength();
                System.out.print("Length 2: ");
                l2.showLength();
                System.out.print("Length 3: ");
                l3.showLength();
                System.out.print("Sum: ");
                sum.showLength();
        }

}

---

I get the following output on my console.

Code:

---

Length 1: 4' 7''
Length 2: 3' 10''
Length 3: 6' 4''
Sum: 14' 9''

Hope this helps...

well if u are entering the 4'7" exactly as the input, u can't expect the ' and " to add it up themself so the first thing to do is to take it away and do the math later

u can use str.charat() and follow by an if to check if it is the ' or "
and to ignore that latter when doing addition
