查寻特定字符串_Java相关

查找特定字符串？
比如：
有个字符串为 abcdef[wx]hijkaaalmn[fn]opqbbbbrst

我现在要得到 [wx]、aaa、[fn]、bbbb 这四个值及他们的索引，怎么实现？

望大家帮帮忙...

------解决方案--------------------------------------------------------
String str ="abcdef[wx]hijkaaalmn[fn]opqbbbbrst"

int newStr = str.indexof("[wx]");
其他同上！

正则表达式

Java code

(\[\w+\])|(\<i\>\w+\<\/i\>)
------解决方案--------------------------------------------------------
Java codeString s = "abcdef[wx]hijk<i>aaa</i>lmn[fn]opq<i>bbbb</i>rst";        String px = "[a-z]*(\\[[a-z]*\\])[a-z]*(<i>[a-z]*</i>)";        Pattern p = Pattern.compile(px);        Matcher m = p.matcher(s);        while (m.find()) {            System.out.println(m.group(1));            System.out.println(m.group(2));        }
------解决方案--------------------------------------------------------
Java codeString scontent="abcdef[wx]hijk<i>aaa</i>lmn[fn]opq<i>bbbb</i>rst";        String rex = "(\\[\\w+\\])|(\\<i\\>\\w+\\<\\/i\\>)";        Pattern p = Pattern.compile(rex);        Matcher m = p.matcher(scontent);        while(m.find()){            System.out.println(m.group());        }
------解决方案--------------------------------------------------------
System.out.println(m.group()+m.start());起始值索引
------解决方案--------------------------------------------------------
for example

Java codeString s = "abcdef[wx]hijk<i>aaa</i>lmn[fn]opq<i>bbbb</i>rst";Pattern p = Pattern.compile("\\[\\w+\\]|(?i)<i\\s*>.*?</i>");Matcher m = p.matcher(s);while (m.find()) {    System.out.println(m.group());}
------解决方案--------------------------------------------------------
Java code      String s = "abcdef[wx]hijk<i>aaa</i>lmn[fn]opq<i>bbbb</i>rst";      Pattern p = Pattern.compile("\\[\\w+\\]|(<i>\\w+</i>)");      Matcher m = p.matcher(s);      while(m.find()) {         System.err.println("index = " + m.start() + ", string = " + m.group());      }

Java code

      String s = "abcdef[wx]hijk<i>aaa</i>lmn[fn]opq<i>bbbb</i>rst";
      Pattern p = Pattern.compile("\\[\\w+\\]|(<i>\\w+</i>)");
      Matcher m = p.matcher(s);

      while(m.find……

------解决方案--------------------------------------------------------
Java codeString str="abcdef[wx]hijk<i>aaa</i>lmn[fn]opq<i>bbbb</i>rst";        Pattern pat=Pattern.compile("(?:\\[.*?\\]|<(.*?)>[^<]+</\\1>)");        Matcher mcr=pat.matcher(str);        while(mcr.find()){            System.out.println(mcr.start()+"    "+mcr.group()+"  "+mcr.end());        }
