Remove first word from a string in Java

Question

What\'s the best way to remove the first word from a string in Java?

If I have

String originalString = \"This is a string\";

I want to r

Answer 1

You can use substring

removedWord = originalString.substring(0,originalString.indexOf(' '));
originalString = originalString.substring(originalString.indexOf(' ')+1);

Answer 2

You can check where is the first space character and seperate string.

String full = "Sample Text";
String cut;
int pointToCut = full.indexOf( ' ');

if ( offset > -1)
{
  cut = full.substring( space + 1);
}

Answer 3

Simple.

 String o = "This is a string";
 System.out.println(Arrays.toString(o.split(" ", 2)));

Output :

[This, is a string]

EDIT:

---

In line 2 below the values are stored in the arr array. Access them like normal arrays.

 String o = "This is a string";
 String [] arr = o.split(" ", 2);

 arr[0] // This
 arr[1] // is a string

Answer 4

For an immediate answer you can use this :

removeWord = originalString.substring(0,originalString.indexOf(' '));
originalString = originalString.substring(originalString.indexOf(' '));

Answer 5

Try this using an index var, I think it's quite efficient :

int spaceIdx = originalString.indexOf(" ");
String removedWord = originalString.substring(0,spaceIdx);
originalString = originalString.substring(spaceIdx);

Prior to JDK 1.7 using below method might be more efficient, especially if you are using long string (see this article).

originalString = new String(originalString.substring(spaceIdx));

Answer 6

You can use the StringTokenizer class.
