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：二元運算子' '的錯誤運算元型別
uj5u.com熱心網友回復：
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());
uj5u.com熱心網友回復：
在這里，您將類亂數的物件添加到此
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);
