Split Function



As J2ME is not supporting split of the String which is possible in J2SE

i am providing a best example for split which i have seen


private String[] split(String original,String separator) {
Vector nodes = new Vector();
// Parse nodes into vector
int index = original.indexOf(separator);
while(index >= 0) {
nodes.addElement( original.substring(0, index) );
original = original.substring(index+separator.length());
index = original.indexOf(separator);
}
// Get the last node
nodes.addElement( original );

// Create split string array
String[] result = new String[ nodes.size() ];
if( nodes.size() > 0 ) {
for(int loop = 0; loop < nodes.size(); loop++)
{
result[loop] = (String)nodes.elementAt(loop);
System.out.println(result[loop]);
}

}
return result;
}



The above method will let you split a string about the passed separator, much like J2EE's String.split(). So first split the string
on the line break tag, and then do it at each offset of the returned array for the "," comma.
e.g.

String[] lines = this.split(myString,"<br>");
for(int i = 0; i < lines.length; i++)
{
String[] splitStr = this.split(lines[i],",");
System.out.println(splitStr[0] + " " + splitStr[1] + " " + splitStr[2]);
}
