Question

我试图用一句话来形容。

你们怎么会把最后一封信分配给一个变数?

我想利用斯堪的班子来平整字,使每封信成为阵列中的一个要素,但斯堪的内尔(S堪的纳)似乎只是用整句话,而不是用个别信件。

任何帮助?

EDIT: Thanks so much for your help guys. It looks like I was overthinking it as I didn t know about charAt(). Much simpler now. Also, i m amazed at how fast the responses are on here, it s a god send especially as I ve got an assignment due in tomorrow and I think I might be in for an all-nighter.

Answer 1

String str = "the rain in spain";
System.out.println(str.charAt(str.length() - 1));

Answer 2

就像你重新思考。为什么不这样做

String x = "abcde";
char y = x.charAt(x.length() - 1);

Answer 3

你们可以使用长处和果园方法。下面是你开始学习的一个例子:

String test = "ABC123";

for (int i = 0; i < test.length(); i++)
{
    char myChar = test.charAt(i);

    // etc.
}

Answer 4

公正使用替代方法和其他简单的java 这些方法非常有用。

int length = inputWord.length();
int last = length-1;
String lastLetter = inputWord.substring(last);

并非非常困难,但你可能认为它过于复杂。
