用JAVA编写1/2+1/3得出来的值

在Java中，你可以使用分数（Fraction）类或者数学库来计算两个分数相加的结果。这里我们可以手动创建一个简单的分数类来演示如何求解1/2 + 1/3。首先，我们需要创建一个`Fraction`类，然后实例化两个分数并相加。

public class Fraction {
    private int numerator;
    private int denominator;

    public Fraction(int numerator, int denominator) {
        this.numerator = numerator;
        this.denominator = denominator;
    }

    public Fraction add(Fraction other) {
        int newNumerator = this.numerator * other.denominator + this.denominator * other.numerator;
        int newDenominator = this.denominator * other.denominator;
        return new Fraction(newNumerator, newDenominator);
    }

    @Override
    public String toString() {
        return numerator + "/" + denominator;
    }
}

// 使用这个类来计算1/2 + 1/3
public static void main(String[] args) {
    Fraction oneHalf = new Fraction(1, 2);
    Fraction oneThird = new Fraction(1, 3);

    Fraction sum = oneHalf.add(oneThird);
    System.out.println("1/2 + 1/3 的结果是: " + sum);
}

当你运行这段代码，你会得到结果 `5/6`，即1/2 加上 1/3 等于 5/6。
