### [`find()`](https://lingcoder.gitee.io/onjava8/#/book/18-Strings?id=find) `Matcher.find()`方法可用來在`CharSequence`中查找多個匹配。例如： ~~~ // strings/Finding.java import java.util.regex.*; public class Finding { public static void main(String[] args) { Matcher m = Pattern.compile("\\w+") .matcher( "Evening is full of the linnet's wings"); while(m.find()) System.out.print(m.group() + " "); System.out.println(); int i = 0; while(m.find(i)) { System.out.print(m.group() + " "); i++; } } } /* Output: Evening is full of the linnet s wings Evening vening ening ning ing ng g is is s full full ull ll l of of f the the he e linnet linnet innet nnet net et t s s wings wings ings ngs gs s */ ~~~ 模式`\\w+`將字符串劃分為詞。`find()`方法像迭代器那樣向前遍歷輸入字符串。而第二個重載的`find()`接收一個整型參數，該整數表示字符串中字符的位置，并以其作為搜索的起點。從結果可以看出，后一個版本的`find()`方法能夠根據其參數的值，不斷重新設定搜索的起始位置。
