Hello all ,

while matching any string using matcher and compiler why find method always gets to the next token which do not exist in the macther argument.

See following code

package javaapplication1; import java.util.regex.*; /** * * @author Admin */ public class Example5 { public static void main(String[] args) { Pattern p = Pattern.compile("\\d*"); Matcher m = p.matcher("ab34ef88f"); boolean b= false; while(b = m.find()) { System.out.println(m.start() + " " +m.group()); } }

This code produces output like :
0
1
2 34
4
5
6 88
8
9

why i get 9 as output there no element at 9th position ?


Thanks

Hello all ,

String s = "abc";
String s2 = new String("abc");

if(s==s2) // this is true

then

String s = "abc";
String s2 = new StringBuffer("abc").toString();
if(s==s2) // this condition will be false

What is the difference between this two codes.

public class ImmutableStrings
{
public static void main(String[] args)
{
String one = "someString";
String two = new String("someString");

one = two = null;
}
}
