print vs println using split method

[Oceana Wickramasinghe]

When using this code

class MySplit{
String matcher="sd23dsf2323sdd";
String pattern="\\d";
void splitString(){
String[]list=matcher.split(pattern);
int x=0;
while(x<list.length){
System.out.print(list[x]);
x++;
}
}
}

class TestMySplit{
public static void main(String[]args){
MySplit ms=new MySplit();
ms.splitString();
}
}

i get the output :sddsfsdd

So its not returning empty strings.

But if i replace print with println

i get the output:

sd

dsf



sdd

Can someone tell me why println prints empty strings but why print doesnt?

println adds a newline after each token. print does not.

So what you are seeing with print is a concatenation of the tokens (including the empty ones "").

try:

System.out.print("[" +list[x] +"]");

But it is.

Try this:

String abc = "abc";
String empty = "";
System.out.print(abc);
System.out.print(empty);
System.out.print(empty);
System.out.print(empty);
System.out.print(abc);

Then try it again with println() instead of print().

Then try both again without any of the "empty" lines.

The println() method prints a String value followed by a line break character. What you're seeing are the line break characters, not the empty String values.

Edit: Dang, way too slow...
