Split问题
public class c
{
public static void main(String [] args)
{
String email = "2451@163.com ";
String [] str = email.split( "@ ");
System.out.println(str[0]);
System.out.println(str[1]);
String [] str2 = str[1].split( ". ");
System.out.println(str2[0]);
System.out.println(str2[1]);
}
}
为什么数组下标越界
[解决办法]
public class c
{
public static void main(String [] args)
{
String email = "2451@163.com ";
String [] str = email.split( "@ ");
System.out.println(str[0]);
System.out.println(str[1]);
String [] str2 = str[1].split( "\\. ");
System.out.println(str2[0]);
System.out.println(str2[1]);
}
}
