String Operations

[ssasi kumar]

Hi Everybody,


i have doubt from string operations. that is normally we can split string using some key words such as stringtokenizer and split functions. But now i want spliting string using general string concepts insteadof stringtokenizer and split keywords.



with regards,
sasikumar


thanks to advane

Hi,

Welcome to CodeRanch!

I'm not quite sure what you might mean by "general string concepts", but perhaps you're thinking of regular expressions? Have a look at the java.util.regex.Pattern class to see if that will meet your needs.

hi guys,
ok i will check java.regex package. but generally using java.regex package concept are understanding java experts only. so if you dont mind how do working normal string concepts using perform to stringtokenizer functions .

Again, I have no idea what you mean by this. Maybe an example would help me?

Have a look at string functions like substring(..) , indexOf(..) , lastIndexOf(..) , charAt(..) etc.

For example , the below code will print 1.

String s = "1,2,3,4";
System.out.println(s.substring(0,s.indexOf(",")));

why not use toArray() ... if regex is not what you are looking for

[Rob Spoor]

Because String does not have a toArray() method perhaps?

what about ... toCharArray() ...

i was just trying to put the logic up not the exact method name ...

anyways thanks Rob ...

toCharArray() should only be used if you really need a char[], because it creates a new char[]. If you only need to access characters from the String you should use length() and charAt(int) instead.

What about this is unclear? What would you expect this to print? Why do you think this is wrong? We can't help you if you don't explain what you think the problem is.

I am clear about what I have pasted in this thread .... but looks like you are not at all clear about "who is asking for help ?" & "what is he asking for ?"

The person who initiated this thread is asking for various ways to split a string without using Stringtokenizer or split() method etc

Anyways thanks for asking me so many questions

Peace

Careful. Those aren't keywords.
