正则应用

将物理地址转换成windows中java可识别的形式：D://Devenv//Server//apache-tomcat-6.0.29//apache-tomcat-6.0.29//webapps//myHand//a.xml­

初级结果：­­

public class Replaces {­

public static void main(String[] args) {­

Stringstr="D:\\Devenv\\Server\\apache-tomcat-6.0.29\\apache-tomcat-6.0.29\\webapps\\myHand\\a.xml";­

String[] str1=str.split("\\\\");­

String sbf=str1[0];­

for(int i=1;i

sbf=sbf "//" str1[i];­

}­

System.out.println(sbf);­

}­

}­

­

最终结果：­

public class Replaces {­

public static void main(String[] args) {­

Stringstr="D:\\Devenv\\Server\\apache-tomcat-6.0.29\\apache-tomcat-6.0.29\\webapps\\myHand\\a.xml";­

str=str.replaceAll("\\\\","//");­

System.out.println(str);­

}­

}

由上看得：正则很重要
