3.我要找出这样的一个字符串，包含is,然后，在is后面跟着一个perfect。
bisb.*bperfectb

package com.pattern.test;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

public class PatternTest {

public static void main(String[] args) {

String pattern = "bisb.*bperfectb";

String testStr = "RegexBuddy is your perfect companion for working with regular expressions";

// pattern = args [0];

// testStr = args [1];

Matcher matcher = Pattern. compile(pattern).matcher(testStr);

if (matcher.find()) {

System. out.println("[" +testStr+"]" + " matches pattern " +"["+ pattern+"]" );

System. out.println("After replace,the new testStr is:[" + matcher.replaceFirst("TARGET" )+"]" );

System. out.println("the origl testStr is:[" + testStr+"]");

} else {

System. out.println("[" +testStr+"]" + " does not match pattern " + "["+ pattern+ "]");

}

}

}

-----
输出：

[RegexBuddy is your perfect companion for working with regular expressions] matches pattern [bisb.*bperfectb]

After replace,the new testStr is:[RegexBuddy TARGET companion for working with regular expressions]

the origl testStr is:[RegexBuddy is your perfect companion for working with regular expressions]
