How to remove a char from string? JAVA

Question

Hello everyone I want to know how can I remove ','s from (for ex.) "42,32,55,77" and add those numbers in an array.

Answer 1

It's called splitting.

String[] parts = myString.split(",");

You'll then have to convert the strings to numbers manually if you need to. One way to do it is

List<Integer> myListOfNumbers = Arrays.stream(parts).map(Integer::parseInt).collect(Collectors.toList());

Answer 2

String Str = new String("1,2,3,4,5");
Str = Str.replace(',', '');
//it's for remove ','

Answer 3

What about array?

Answer 4

oh I have founded the split and wanted to ask about making them integers and I have got this message. Thanks a lot guys!
