Java 利用 split 方法切割字符串

 1         // 以空格切割
 2         String s1 = "dew qefdewrfr freqg gtrh yt hy";
 3         String[] words1 = s1.split("\\s+");
 4 
 5         // 以 . 切割
 6         String s2 = "dew.qefdewrfr.freqg.gtrh.yt.hy";
 7         String[] words2 = s2.split("\\.");
 8 
 9         // 以 * 切割
10         String s3 = "dew*qefdewrfr*freqg*gtrh.yt.hy";
11         String[] words3 = s3.split("\\*");
12 
13         // 以 " 切割
14         String s4 = "dewqe\"fdewrfr\"freqg.gtrh.yt.hy";
15         String[] words4 = s4.split("\\\"");
16         //String[] words44 = s4.split("\"");
17 
18         // 以普通字符 ‘（f） 切割
19         String s5 = "dew‘qefdewrfr‘freqg.gtrh.yt.hy";
20         String[] words5 = s5.split("‘");
21         String[] words6 = s5.split("f");
22 
23         for(String s: words4) {
24             System.out.println(s);
25         }
