Hi Friend,

Try the following code:

public class RationalClass{
private int nr;
private int dr;

public RationalClass(int numerator, int denominator) {
if (denominator == 0) {
throw new RuntimeException("Denominator is zero");
}
int no = rationalNumber(numerator, denominator);
nr = numerator / no;
dr = denominator / no;

}
public RationalClass add(RationalClass number) {
int numerator = (this.nr * number.dr) + (this.dr * number.nr);
int denominator = this.dr * number.dr;
return new RationalClass(numerator, denominator);
}

public RationalClass subtract(RationalClass number) {
int numerator = (this.nr * number.dr) - (this.dr * number.nr);
int denominator = this.dr * number.dr;
return new RationalClass(numerator, denominator);
}
public RationalClass multiply(RationalClass number) {
return new RationalClass(this.nr * number.nr, this.dr * number.dr);
}
public RationalClass divide(RationalClass number) {
return new RationalClass(this.nr * number.dr, this.dr * number.nr);
}
private static int rationalNumber(int p, int q) {
if (q==0){
return p;
}
else{
return rationalNumber(q, p % q);
}
}
public String toString() {
if (dr == 1){
return nr + "";
}
else{
return nr + "/" + dr;
}
}
public static void main(String[] args) {
RationalClass a, b, c;

a = new RationalClass(1, 2);
b = new RationalClass(1, 2);
c = a.add(b);
System.out.println("Addition= "+c);

a = new RationalClass(1, 2);
b = new RationalClass(1, 2);
c = a.subtract(b);
System.out.println("Subtraction= "+c);

a = new RationalClass(1, 2);
b = new RationalClass(1, 2);
c = a.multiply(b);
System.out.println("Multiplication= "+c);

a = new RationalClass(1, 9);
b = new RationalClass(1, 3);
c = a.divide(b);
System.out.println("Division= "+c);
}
}

Thanks
