I wish to split a string xxx/yyyy/zzz so that ...

**nmvictor** · 10-22-2009, 04:38 PM

Hi, I wish to split a string xxx/yyyy/zzzz so that the parts xxx yyyy and zzzz are returned as seperate strings on their own.Currently i am using the code below though i feel like their could be a better option with the method

Java Code:

 split( )

here what im using

Java Code:

//method to split xxx/yyyy/zzzz as seperate strings...
public void getXYZ( )
{ 
String str = "xxx/yyyy/zzzz";
String x,  //for the xxx part
         y,  //for the yyyy part
         z;  //for the zzzz part
x = str.substring(0,2);
y = str.substring(4,8);
z = str.substring(10,13);
}

I know some java geek has a better idea to this,possibly using

Java Code:

 split( )

, that will be really appreciated .Thanks in advance

Yep, use String.split(regex)

How???? I know their exists split ( ) but I don't know how to use it, that's why I posted the thread.Isn't this New to Java category?

According to the API documentation: str.split("/") does the job, i.e. it returns a String[] containing the String parts you're looking for.

kind regards,

Though this forums I gathered some ideas and came up with the code below,

Java Code:

public class TestString {

public void doit() {
 	String str = "xxx/yyyy/zzzz";
 	String [] temp = null;
 	temp = str.split("/");
 	dump(temp);
}

public void dump(String []s) {
 	for (int i = 0 ; i < s.length ; i++) {
 		System.out.println(s[i]);
        String x = s[i];
 	}
}

public static void main(String args[]) throws Exception{
  	TestString ss = new TestString();
             ss.doit();
}
  }

output:
xxx
yyyy
zzzz

Now that is perfect except the string except they are printed to system.out meaning i cant do much with them other than see them, is their a way I can modify the above so that xxx, yyyy and zzz are returned as values of a separate String variable which I can use in other methods within my project.

You can pass them as a String[], which will have "xxx", "yyy", and "zzz" as elements (like you did for your dump method).

What do you want to do with the values? Most of the time, you parse a String for a reason - this reason will tell you how to best store the three parts.

The new for-loop can make it look fancy:

Java Code:

for (String part : "xxx/yyyy/zzzzz".split("/"))
   // do anything with the 'part' String here ...

Thanks to all who are helping me out, how about having these parts(

Java Code:

xxx, yyy, zzz

split from

Java Code:

 xxx/yyyy/zzzz

assigned as values of three string variables?Actually what I want do is to send these three parts into three separate fields in a database, so of course I want to include the variables in the SQL statement and not the exact values.Any further help will be appreciated.:cool:

Read the API documentation for the PreparedStatement interface; you can 'inject' values in the String form of SQL queries without the need to fiddle with Strings yourself (and protect yourself from malicious "SQL injection" hacks).

I appreciate whatever suggestions you give, what's the code anyway, to a newbie in Java,suggestions without the code don't really help much or should I start another thread on how can I "'inject' values in the String form of SQL queries without the need to fiddle with Strings"?Sorry if I'm sounding rude.

You don't learn if source code is spoonfed to you; have you read the API documentation for the PreparedStatement? I don't give you a fish, I attempt to teach you how to fish.
