How to split a String using split function

[Java Tip]

This tip will show the use of split function to split a String according to particular separator character.

In this program Split() function is splitting the String according to ‘:’.

public class StringSplit {
 
public void doit() {
 	String str = "CompChamps:Guys:are:There";
 	String [] temp = null;
 	temp = str.split(":");
 	dump(temp);
}

public void dump(String []s) {
 	for (int i = 0 ; i < s.length ; i++) {
 		System.out.println(s[i]);
 	}
}
}
public static void main(String args[]) throws Exception{
  	StringSplit ss = new StringSplit();
             ss.doit();
}

Try this code :

public class splitdemo {

private static String REGEX = ":";
private static String INPUT = "CompChamps:Guys:are:There";
public static void main(String[] argv) {
/*A compiled representation of a regular expression.
regular expression, specified as a string, must first be compiled into an instance of this class.*/
Pattern p = Pattern.compile(REGEX);
// editing your input file, regex.txt
String[] items = p.split(INPUT);
for (int i = 0; i < items.length; i++) {
System.out.println(items[i]);
}
}
}

A shorter example

public class StringSplit {
    public static void main(String[] argv) {
        System.out.println(Arrays.asList(
            "CompChamps:Guys:are:There".split(":")));
    }
}
