Is there a way to split a string after a certain number of characters in Java?

Question

Say I have a string "yyyymmddword", Is there a method I could use to have an int year, month, day, and String word based on that string. So if I have a string "20070405word", I need to convert it to:

String name = "yyyymmddword";
int year = 2007;
int day = 04;
int month = 05;
String word = "word";

How can I write a method that can allow me to split that string without manually assigning these variables?

Answer 1

To base purely off the index of the character String.substring() is perfectly suitable.

public static void main(String args[]) {
    String s = "yyyymmddword";

    System.out.println(s.substring(0,4));
    System.out.println(s.substring(4,6));
    System.out.println(s.substring(6,8));
    System.out.println(s.substring(8));        
}

Output:

yyyy
mm
dd
word

Answer 2

Try this:

String name = "yyyymmddword";
int year = Integer.parseInt(name.substring(0, 4));
int day = Integer.parseInt(name.substring(4, 6));
int month = Integer.parseInt(name.substring(6, 8));
String year = Integer.parseInt(name.substring(8));

Answer 3

Yes there is. All you need to do is create more Strings, then use the substring() method. Follow my example below.

    String word = "TestString";
    String new1 = word.substring(0,4); 
    /*substring() goes from the first specified index, up to, but not including
    * the second.
    */
    String new2 = word.substring(4,word.length() + 1);
    System.out.println(word + "\n" + new1 + "\n" + new2);
