Splitting text in Java

SPLITTING TEXT IN JAVA Shene J Jamal

Splitting a text • Generally, there are two ways to split a string in Java

1- By using an object from StringTokenizer which belongs to the package java.util.StringTokenizer.

2- By using the Split() methods which belongs to the Java String class.

StringTokenizer • Used to split a String into different tokens by a defined

delimiter. (space is the default delimiter)

String str = "This is String Tokenizer Example"; StringTokenizer st = new StringTokenizer(str); while (st.hasMoreElements()) { System.out.println(st.nextElement()); }

StringTokenizer • A delimiter could also be defined

String str = "This is a String| Tokenizer| Example"; StringTokenizer st = new StringTokenizer(str, ”|”); while (st.hasMoreElements()) { System.out.println(st.nextElement()); } • Tokenizer returns one token at a time

Using split methods • There are two split methods Java String class. • A split method returns an array of string.

String input = “Hello- we are- trying to split a text- using Split methods"; String[]records = input.split(“-"); //OR String[]records = input.split(“-“, 2); The second argument is the limit.
