java split method not working as expected

Hi, I am facing this small issue on the split method in java. Not sure this is a known one or not.. please help.

Java

String tmp = "Hello I      am fine   ";
String str[] = tmp.split(" ");
System.out.println("STR[0] => " + str[0]);
		
String tmp1 = "  Hello I      am fine   ";
String str1[] = tmp1.split(" ");
System.out.println("STR1[0] => " + str1[0]);

Output as below:

VB

STR[0] => Hello
STR1[0] =>

As you can see, if there is a space before "hello" word, this is happening.. is there is any workaround for this? I know that split takes regex as argument, but still there has to be a way to skip the first empty space if it exists before the word ? right?

Thanks in advance.

Try triming the string before splitting. Trmming will remove all the leading and trailing whitespaces.

Java

String tmp = "Hello I      am fine   ";
String str[] = tmp.trim().split(" ");
System.out.println("STR[0] => " + str[0]);

String tmp1 = "  Hello I      am fine   ";
String str1[] = tmp1.trim().split(" ");
System.out.println("STR1[0] => " + str1[0]);
