What is the method to omit a string in java?

Hi,  

 

Olivia hope the following steps will guide you in fixing of this issue.

 

• Using Strings in the Java  the parsing is done by the use of the split () which can be from the String class.

• StringTokenizer is also the function that can also be used in parsing a string as we mostly don't use it due to some disadvantages present in this StringTokenizer.

• This may give just in brief overview available in some of the common as well as easiest ways in using the split method.

• For more on this Strings its better to go through with the Java API documentation for especially split.

• Example is as follows.

Public class TestStringSplit {

    public static void main(String[] args) throws Exception {

        String s = "1,2,,,,,,3 4 5,,,,,,";

        String[] a = s.split(",");

        System.out.println("Length of array: " + a.length);

        for (int i = 0; i < a.length; i++) {

            System.out.println("Part[" + i + "]: '" + a[i] + "'");

        }

        a = s.split(",", -1);

        System.out.println("n======nLength of array: " + a.length);

        for (int i = 0; i < a.length; i++) {

            System.out.println("Part[" + i + "]: '" + a[i] + "'");

        }

    }

}

 

Output:–>

Length of array: 8

Part[0]: '1'

Part[1]: '2'

Part[2]: ''

Part[3]: ''

Part[4]: ''

Part[5]: ''

Part[6]: ''

Part[7]: '3 4 5'

 

======

Length of array: 14

Part[0]: '1'

Part[1]: '2'

Part[2]: ''

Part[3]: ''

Part[4]: ''

Part[5]: ''

Part[6]: ''

Part[7]: '3 4 5'

Part[8]: ''

Part[9]: ''

Part[10]: ''

Part[11]: ''

Part[12]: ''

Part[13]: ''

 

Thank you..:-)
