必须使用java生成随机数，并将随机数传递给xml变量。还需要计算它的加法

必须使用java生成3个随机数，并将生成的值传递给现有的xml文件变量。
并且需要在xml文件中计算加法和乘法，并且需要在控制台中打印值

这里我得到了生成随机数的代码。有人能帮我吗

package test_package;

import java.util.Random;

public class Random_Number_Generation {
    public static void main(String args [] ) {

        Random randomGenerator = new Random();
        for (int i = 1; i <= 3; i++){
            int randomInt = randomGenerator.nextInt(100);
            System.out.print("\nRandom Number is :" + randomInt); 
        }
    }
}

package-test\u-package；
导入java.util.Random；
公共类随机数生成{
公共静态void main（字符串参数[]）{
Random randomGenerator=新的Random（）；
对于（int i=1；i，这里有一个使用jaxb创建xml的简单示例。在这个示例中，方法：

fromXml（字符串xml）
-将xml字符串解组到XMLObj

toXml（字符串xml）
-将XMLObj封送为字符串

    <randomNumberTwo>98</randomNumberTwo>
</xml-gen>

Added Another random Value
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xml-gen>
    <calculatedValue calculatedValue="92">51 + 98 - 57</calculatedValue>
    <randomNumberOne>51</randomNumberOne>
    <randomNumberThree>57</randomNumberThree>
    <randomNumberTwo>98</randomNumberTwo>
</xml-gen>

原始值
51
57
98
添加了另一个随机值
51 + 98 - 57
51
57
98
你需要什么帮助？我想你需要对XML做些什么？@Naman gala我需要上面的代码。你能帮忙吗？谢谢你的帮助，这段代码对我很有用。我想增强这段代码，就像XML文件已经存在一样。在这段代码中应该有3个变量。我必须生成3个随机数，并且需要将随机值传递给XML变量。Also计算应该在xml文件中进行。您能在这方面帮助我吗？xml是一个字符串，因此您不能在xml中计算，但是您可以更改
getRandomNumber（）的getter
调用您的随机数生成器方法。计算也应在xml文件中进行。您对此有要求吗，我认为这是HOMEWRK？1。要求类似于将有3个字段，随机生成的值必须通过使用java语言的测试自动化工具输入字段。基于这3个变量lues第四个字段将填充/计算值（如加法、乘法）我们必须在XML文件中定义变量和公式，该文件已存在于项目根文件夹中。2.使用Testng可以在XML中进行计算？我不理解这一要求…我们必须在XML文件中定义变量和公式，该文件已存在于项目根文件夹中，您刚刚看到了吗需要在xml中显示第四个值是如何计算的？是的，我们必须显示计算的值。因为这是违反知识产权的，我不能在这里分享这一要求。我们有一个作为xml文件的现有项目区域。必须传递随机值，并且必须进行计算。
