java中怎样从一系列字符串中读取小数？例如14.2、0.0
java中怎样从一系列字符串中读取小数？例如14.2、0.0

------解决方案--------------------
import java.util.*;
public class Fenxi
{
public static void main(String args[])
{
String str = "we are students 14.2,0.0 ";
StringTokenizer fenxi= new StringTokenizer(str, " , "); //以空格和逗号分
int len = fenxi.countTokens();
while(fenxi.hasMoreTokens())
{
String s = fenxi.nextToken();
StringBuffer temps = new StringBuffer();
char sr[] = s.toCharArray();
for(int i = 0;i <sr.length;i++)
{
if(Character.isDigit(sr[i]) || (sr[i] == '. '))
temps.append(sr[i]);
}
if(temps.length() != 0)
System.out.println( " " + new String(temps));
}
}
}

临时写了一个，也满足要求了，嘿嘿
