Java split string, the first char is a space

[new_cyber]

Hi guys,
I'm doing 2 splits from a txt file, the 1st split saves the 1st char of the file
the next split saves the rest of the line.
For example the line is:
"Ab Just an example"
The first split saves.me the word "Ab" but the other split saves the phrase:
" Just an example" the thing is that I get an empty space in the begining of the phrase, what I need to change?

The code that I'm using is:

firstChar=txtFile.next().split(" ");
theRestPhrase=txtFile.nextLine().split("\n");

Thanks and sorry my poor english.
Regards

I think you mean you are trying to get the first word and then the rest of the line.

split() actually returns an array of strings so it's a bit hard to understand the code you posted. Perhaps you could post a small compilable example that is giving the undesirable output?

Yes, that What I want, to get the firsd word and then the rest of the line.
I'm using a file reader, the thing is , I'm reading a .txt file, the first split

firstChar=txtFile.next().split(" ");

saves the frist word and I do other split to save the rest of the line

theRestPhrase=txtFile.nextLine().split("\n");

and it works, but the begining of the rest of the line is an empty space and I want to remove the empty space but I dont know how.

ok do this:

String myString = "Ab Just an example";
String firstWord, restOfString="";

String[] aSplit = myString.split(" ");

firstWord=aSplit[0];

// now for the rest of string we can just append the rest
for (int i=1; i<aSplit.length; i++)
{
    restOfString += aSplit[i];
    restOfString += " ";
}

System.out.println("First word = [" + firstWord + "]");
System.out.println("Rest of string = [" + restOfString + "]");

output

First word = [Ab]
Rest of string = [Just an Example]

System.out.println("Rest of string = [" + restOfString + "]");

output

First word = [Ab]
Rest of string = [Just an Example]

Thanks mate, it worked.

Thanks mate, it worked.

Do you understand how to use .split() from my example now?

it's a lot easier to make arrays and use arrays on the string.split() then trying to use scanner and split combined.

if you want to use scanner then use the scanner.Delimiter(" "); method, it will do your way of trying to break it up. (.next() & .nextLine())

Just look up the Scanner API

Yes, looking the example you gave me, I modified my code and it works now , really apreciate your help.

Have a happy new year.

A more accurate approach would be to avoid arrays and use String methods: indexOf() will find the first space and the two variants of substring() will enable the word and the rest of the line to be extracted. trim() might also be useful when dealing with the second part.

And another way of doing it.

import java.util.Scanner;
public class stringTest 
{
    public static void main(String[] args) 
    {
        String abc = "Abc Rest of String goes here";
        String firstWord, restOfString;
        Scanner sc = new Scanner(abc);
        
        firstWord = sc.next();
        restOfString = sc.nextLine();
        
        System.out.println(firstWord);
        System.out.println(restOfString);
        
        restOfString = restOfString.substring(1,restOfString.length());
        //    restOfString = restOfString.trim();   = less typing :D
        System.out.println(restOfString);
    }
}
