Hello,

I am stuck, please help. I am looking for a simple java program that can convert string to string array and also want to know how to pass the string parameter to java program and return a string array from other java application.
For example the input parameter will be string like 1;2;3;4;5 , return a string array 1,2,3,4,5

Thank you all

I mean, could you please give an example of how to call this from other application and i think we need to create a jar file.  In order to make use of the example you provided don't i need to put the method you provided in a class and make a jar file.

public class Steve {
   public static String[] toArray(String s) {
      String[] array = s.split(";");
      return array;
   }
}


you can call it from another class using:

String s = "1;2;3;4;5";
String[] array = Steve.toArray(s);
System.out.println(Arrays.toString(array));   // convert array back to string to display output
