实现rational类的可比较接口(Java)

public class Rational implements Comparable<Rational> {
    // 类的实现代码
}

@Override
public int compareTo(Rational other) {
    // 比较逻辑的实现代码
}

@Override
public int compareTo(Rational other) {
    int thisNumerator = this.getNumerator();
    int thisDenominator = this.getDenominator();
    int otherNumerator = other.getNumerator();
    int otherDenominator = other.getDenominator();

    // 比较逻辑的实现代码

    // 如果当前对象大于other对象，返回正整数
    // 如果当前对象等于other对象，返回0
    // 如果当前对象小于other对象，返回负整数
}

@Override
public int compareTo(Rational other) {
    int thisNumerator = this.getNumerator();
    int thisDenominator = this.getDenominator();
    int otherNumerator = other.getNumerator();
    int otherDenominator = other.getDenominator();

    int diff = thisNumerator * otherDenominator - otherNumerator * thisDenominator;

    if (diff > 0) {
        return 1;
    } else if (diff < 0) {
        return -1;
    } else {
        return 0;
    }
}
