Question

Hello I was wandering how can I copy a piece of a String in Java until a character/symbol is found.
In my case the original string is: "hello.1234" and I want only "hello", so that every thing after the symbol . is discarded.

Any idea? many thanks

EDIT:

solved as follows:

String partBeforeFullStop = input.split("\\.")[0];

Use String#indexOf(int) and String#substring(int).

String input = "hello.1234";
String output = input.substring(0, input.indexOf('.'));
