How to find the number of newlines and word separated by "," in Java?

My string variable contains a String, each on a different line. How do I find the number of new lines in it, and then each word separated by a , delimiter on a particular string line? The variable content is something like below

null37,Abhishek,ARS,b,ABC,Development,2011-05-30 00:00:00.0,abhishek123@cjb.net
null38,Abhishek,SAS,c,ABC,Development,2011-05-30 00:00:00.0,abhishek1开发者_JAVA技巧23@cjb.net
null39,Abhishek,DGV,a,ABC,Production,2011-05-30 00:00:00.0,abhishek123@cjb.net

Edited:

I tried this

String xmlstr="""null37,Abhishek,ARS,b,ABC,Development,2011-05-30 00:00:00.0,abhishek123@cjb.net
null38,Abhishek,SAS,c,ABC,Development,2011-05-30 00:00:00.0,abhishek123@cjb.net
null39,Abhishek,DGV,a,ABC,Production,2011-05-30 00:00:00.0,abhishek123@cjb.net"""

String[] splitStr = xmlstr.split('\n');
for(String str : splitStr)
{
    String splitted = str.split(',');
    println splitted
}

I am getting something unknown,

[Ljava.lang.String;@148bd3
[Ljava.lang.String;@a4e743
[Ljava.lang.String;@4aeb52

To get the number of newlines do

int newLines = myString.split("\\r?\\n").length;

To get each word separated by a comma do

String[] words = myString.split(",");

You could also use Groovy's splitEachLine method.

It works like this:

String xmlstr = """null37,Abhishek,ARS,b,ABC,Development,2011-05-30 00:00:00.0,abhishek123@cjb.net
null38,Abhishek,SAS,c,ABC,Development,2011-05-30 00:00:00.0,abhishek123@cjb.net
null39,Abhishek,DGV,a,ABC,Production,2011-05-30 00:00:00.0,abhishek123@cjb.net"""

xmlstr.splitEachLine( /,/ ) { tokens ->
  println "${tokens[1]} : ${tokens[7]}"
}

That prints out:

Abhishek : abhishek123@cjb.net
Abhishek : abhishek123@cjb.net
Abhishek : abhishek123@cjb.net

Your mistake was only that

String splitted = str.split(','); // Wrong

should have been an array:

String[] splitted = str.split(','); // Fixed

When a Java program prints arrays, the first character is L followed by the class, and then the object's memory location.

Here's some Java code that will compile so you can see the problem that scripting languages hide:

String[] lines = originalString.split("\\r?\\n")); // Do this only once

int numberOfNewLines = lines.length;
int myLine = 5; // Say

String[] words = lines[myLine];

You could easily wrap these idea up in some clean code.

new line char is '\n'. so you should first split by '\n' . then split by ',' .

String[] splittedByNewLine = originalString.Split('\n');

for(String str : splittedByNewLine )
{
   String[] splittedByComma = str.split(',');
   for(String str : splittedByComma )
   {
       "println str..."
   }       
}
