这段代码与前面的示例非常相似,只是使用了ThreadLocalRandom.current().nextInt()方法来生成随机索引。 方法三:使用Collections.shuffle()方法 如果我们不关心每次获取元素时的顺序,而只是想随机排列整个List,然后按照顺序遍历,我们可以使用java.util.Collections.shuffle()方法。这个方法将会随机打乱List中的元素顺序。 以...

However,ifnis an odd number, all its factors must be odd numbers too. For example, 99’s factors are 1, 3, 9, 11, 33, and 99. Therefore, all of them are odd numbers. So, we can adjust the loop’s increment step depending on whethernis odd.As our loop begins fromi = 1, if ...

I wanna sort a List that contains words and numbers. I have a solution already, but I am sure there is a better way around to do this with Lambdas aswell.
