如何對int隨機數和雙隨機數求和？

Question

這是代碼：

    Random randomNumber = new Random();
    System.out.println(randomNumber.nextInt(10));
    Random randomNumberTwo = new Random();
    System.out.println(randomNumberTwo.nextDouble());
    System.out.println(randomNumber + randomNumberTwo);

終端說：java：二元運算符'+'的錯誤操作數類型

Answer 1

randomNumber 和 randomNumberTwo 是生成器，因此為了添加它們，您需要從中生成下一個值：

Random randomNumber = new Random();
Random randomNumberTwo = new Random();
System.out.println(randomNumber.nextInt(10) + randomNumberTwo.nextDouble());

Answer 2

在這里，您將類隨機數的對象添加到此

  Random randomNumber = new Random();
   int a = randomNumber.nextInt(10)
    System.out.println(randomNumber.nextInt(10));
    Random randomNumberTwo = new Random();
    double b = randomNumberTwo.nextDouble()
    System.out.println(randomNumberTwo.nextDouble());
    System.out.println(a + b);
