How to remove the first index of string array in Java?

August 31, 2022

I want to make this text below

String text = "  good morning  \t\thow  \n\nare you    today ";

become

[good, morning, how, are, you, today]

I have tried to split it using .split(["\\s+"]) but it still count the whitespace at the start of the text and store it to array.

String text = "  good morning  \t\thow \n\nare you today ";
String[] items = text.split("\\s+");
System.out.println("Items  = " + Arrays.toString(items));

This is the result I get

Items  = [, good, morning, how, are, you, today]

I have tried using items.remove(0) but the first index still can’t be removed. How to erase the first index?

>Solution :

Use trim() to remove the leading and trailing whitespace before splitting the string.

String text = "  good morning  \t\thow \n\nare you today ";
String[] items = text.trim().split("\\s+");
System.out.println("Items  = " + Arrays.toString(items));
