截取一个字符串的一部分，
ASP中是用left函数，JSP呢
用什么函数？谁能指教?

[asper]

public String substring(int beginIndex)

[ender]

同意……

[mirong]

怎么只有一个参数，找子窜，当然是要两个参数，一个start，一个end。

[hh_ch]

用StringTokenizer来截取，
例如截取2001-5-6 08：08：08字符串中的前2001-5-6，
<%@ page import="java.sql.*" %>
<%@ page import="java.util.*" %>
<% String date="2001-5-6 08:08:08";
StringTokenizer tokens=new StringTokenizer(date);
String a=tokens.nextToken();
String b=tokens.nextToken();
out.println("<b>a="+a);
out.println("<b>b="+b);
%>

谢谢各位

好像不行吧，你能写完整点吗？

[ender]

老大，你从来不看JDK的文档的？？？

public String substring(int beginIndex)
Returns a new string that is a substring of this string. The substring begins with the character at the specified index and extends to the end of this string.
Examples:
"unhappy".substring(2) returns "happy"
"Harbison".substring(3) returns "bison"
"emptiness".substring(9) returns "" (an empty string)

public String substring(int beginIndex,int endIndex)
Returns a new string that is a substring of this string. The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. Thus the length of the substring is endIndex-beginIndex.
Examples:
"hamburger".substring(4, 8) returns "urge"
"smiles".substring(1, 5) returns "mile"

对不起，不是每个人都送，有些人我已经送了，不过不多，本人分数有限。

[handbread]

怪怪。。。。
