can we use multiple matcher objects in one class? I tried to do so, i had no compile time errors but i'm geting the "java.lang.IllegalStateException".. The code is below:
import java.util.regex.*;
public class CharClass {
public static void main(String[] args) {
Pattern p = Pattern.compile("[^abc]");
Matcher m = p.matcher("adbcalsdics");
while (m.find()) {
System.out.println(m.start() + " " + m.group());
}
Pattern p1 = Pattern.compile("[123]");
Matcher m1 = p1.matcher("12343fery65e@(%^G");
while (m1.find()) {
System.out.println("Secong matcher object" + m.start());
}
}
}
output:
1 d
5 l
6 s
7 d
8 i
10 s
Exception in thread "main" java.lang.IllegalStateException: No match available
at java.util.regex.Matcher.start(Unknown Source)
at gameOn.CharClass.main(CharClass.java:16)

You are getting start index on matcher(m) not on m1
System.out.println("Secong matcher object" + m.start());
I know it's a very late reply ;)

@@UdayKumar-df9so yes u r right change that m object

[@megha_s_music]

I have a doubt when while condition goes false then too how it executes further? ?

[@karthikgolagani6844]

+Megha Sahu the while lop will execute as long as the condition stays true,,if the condition is found to be false the loop does'nt execute at all.

[@maravarmanmanoharan3300]

if(m.find()== true){
while (m.find())
{
System.out.println(m.start()+"----"+m.group());
//System.out.println("yes");
}
}
else{
System.out.println("Not Matching");
}
This will execute your desired output but It is not needed
