英文:
How can I find out the number of characters in a String in Java?
问题
这是一个简单的问题，但我在研究方面不太擅长。
我正在尝试找出String中的字符数，并将其放入一个int变量中。例如：
String word = "Hippo";
int numOfCharacters = （告诉我单词中有多少个字符的代码）;
然后以后可以使用那个数字。
英文:
This is a simple question but I'm not very good at research.
I'm trying to find out the number of characters in a String and put it in an int variable. For example:
String word = "Hippo";
int numOfCharacters = (the code that tells me how many characters in the word);
And then use that number later.

relevant JavaDoc会告诉你，length()是你要寻找的方法。因此，word.length();会返回word的大小，这正是你想要的。
英文:
The relevant JavaDoc will tell you that length()is the method you're looking for. So word.length(); would return the size of word, which is what you want.

使用 .length() 来获取字符串中字符的数量
String word = "Hippo";
int numOfCharacters = word.length();
英文:
Use the .length() to get the number of characters in a String
String word = "Hippo";
int numOfCharacters = word.length();
