array of structure of strings

Question

how can i store multiple strings in single array element in java? The strings may be added or deleted dynamically. So, the array has to be flexible. I mean, if there is an array a[], then:

 a[1] should be able to accommodate "String1", "String2", ....  
 a[2] should be able to accommodate "String3", "String4", ....

These strings may be deleted at any time and additional strings can be added any time. What java component supports this kind of functionality? I am new to java and weak at basics. Hope u can help. Thanks !

For real answer, more context is needed. With that info, a container containing containers containing strings is what you need, but which container classes you should use, impossible to say. — hyde

You probably need something like List<List<String>> yourList ;

Remove "String2" from your List:

yourList.get(0).remove("String2");

Add "StringX" to your List at index 0.

 yourList.get(0).add("Stringx");

how do you access a particular string like "String1" in yourList(0) and how do you iterate thru all the strings in yourList(0) ? yourList(0) denotes all stings in array element 0

My suggestion is to try and learn Java collections!

Official Tutorials

Tutorial 1 Tutorial 2

This way you will have a collection for any situation you find yourself in

You can add this strings in the same string using some using a character as delimiter and after that use a split method.

Use Jagged arrays. I can get a program to you to know the basics of jagged arrays: Jagged Arrays – Varying Column Size Arrays
