特殊情况有 * ^ : | . \
一、单个符号作为分隔符
String[] splitAddress=address.split("\\");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
String[] splitAddress=address.split("\\|"); //如果以竖线为分隔符，则split的时候需要加上两个斜杠【\\】进行转义
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
String[] splitAddress=address.split("\\*");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
String[] splitAddress=address.split("\\:");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
String[] splitAddress=address.split("\\.");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
String[] splitAddress=address.split("\\^");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
String[] splitAddress=address.split("@");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
String[] splitAddress=address.split(",");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
二、多个符号作为分隔符
String address="上海^上海市@闵行区#吴中路";
String[] splitAddress=address.split("\\^|@|#");
System.out.println(splitAddress[0]+splitAddress[1]+splitAddress[2]+splitAddress[3]);
例：
String address = new String("192.168.13.240");
String[] str = address.split("\\.");
for(String s : str){
System.out.println(s);
}
输出格式：
192
168
13
240
总结：
（1）split表达式，其实就是一个正则表达式。* ^ | 等符号在正则表达式中属于一种有特殊含义的字符，如果使用此种字符作为分隔符，必须使用转义符即\\加以转义。
（2）如果使用多个分隔符则需要借助 | 符号，如二所示，但需要转义符的仍然要加上分隔符进行处理
