how to replace a char within a string with "nothing"

Question

String mine = sc.next();
        String corrected = mine.replace('.', '????');
        System.out.println(corrected);

that's my code. let's assume that my input on String corrected is "<..><.<..>>" , and I want to replace every "." with a null space, so I get an output like "<><<>>". is there any way to do it?

just use an empty string `mine.replace('.', '')` – Nick May 16 '20 at 00:40 — Nick, May 16 '20 at 00:40

If you want to replace . with an empty ("") string, you can just do:

mine.replace(".", "");

Alternatively, you can also check .replaceAll()

oh this actually worked, i was using these ' ' instead of " ", so I was getting an error. Thanks =) – Alex May 16 '20 at 00:44
`String#replace` takes either a `char` or a `CharSequence`. – VHS May 16 '20 at 00:46

Try this to replace all occurrences of . with empty:

mine.replaceAll("\\.", "")

If you don't want any method, you can do it like this.

String str = "<<.>>.<>.<<.";
String [] parts = str.split("\\.");

for(String s:parts){
    System.out.print(s);
}

Because I tried the method replaceAll(".", "") ; But that method does not allow empty or null spaces in a string. I don't know if it's the best way, but that's what I can think of.
