How to extract all numbers from a string in java?
Suppose the String is n
then array s will contain all the numbers present in the String
String n=sc.next();
String[] s = n.split("[a-zA-Z]+");
eg
n=“abc1defghi23jvkfbd57jnfbddj9”
then s will be
1,23,57,9

String str=“sdfvsdf68fsdfsf8999fsdf09”;
String numberOnly= str.replaceAll("[^0-9]", “”);
anything other then 0-9 will be replaced even the , ? ! and all other things .
can we do the same thing with cpp or python?
