java实现两个分数相加的程序
class Fraction
{
private int fenzi1;
private int fenmu1;
private int fenzi2;
private int fenmu2;
}
public Fraction(int fenzi1,int fenmu1,int fenzi2,int fenmu2)
{
this.fenzi1 = fenzi1;
this.fenzi1 = fenzi1;
this.fenzi2 = fenzi2;
this.fenzi2 = fenzi2;
}
public void Fraction add(int fenzi1,int fenmu1,int fenzi2,int fenmu2)
{Fraction.fenzi1 = this.fenzi1 + fenzi1;
Fraction.fenmu1 = this.fenmu1 + fenmu1;
Fraction.fenzi2 = this.fenzi2 + fenzi2;
Fraction.fenmu2 = this.fenmu2 + fenmu2;
return ;
}
public void display(int fenzi1,int fenmu1,int fenzi2,int fenmu2)
System.out.println(fenzi1+"/"+fenmu1"+"+ fenzi2= "+"/" + fenmu2=);
return;
class Xunlian
{
public static void main(String[] args);
{
Fraction fenshu1 = new Fraction (3,4);
public void Fraction add(int fenzi,int fenmu)
public display(int fenzi,int fenmu);
}
}
求高手帮忙改下程序，或给我一个完整的程序，用结构体实现两个分数的加减，万分感谢
[解决办法]

}

}

this.denominator = denominator;
}
public Fraction add(Fraction summand) {
if (this.denominator % summand.getDenominator() == 0) {

summand.setDenominator(this.denominator);
} else if (summand.getDenominator() % this.denominator == 0) {

}
@Override

}
public static void main(String[] args) {

Fraction b = new Fraction(7, 12);
System.out.println(a.add(b));
