I tried below to use substring but it can use for get integer How can I get only 10.135.57.1/24 ?

Answer 1

For this string the following approach will work:

String[] parts = "10.135.57.1/24 05492518979".split(" ");
String partThatYouNeed = parts[0];

Answer 2

In the substring method you're defining which subsection of the String you're after.

If you did the following you'd get your result:

String whatYouWant = "10.135.57.1/24 05492518979".substring(0, 14);

Answer 3

Or using substring

String yourString = "10.135.57.1/24 05492518979";
int index = yourString.indexof(" ");
String partThatYouNeed = yourString.substring(0,index);

Answer 4

How about this :-)

"10.135.57.1/24 05492518979".replaceFirst(" \\d+$", "")

or this:

"10.135.57.1/24 05492518979".replaceFirst(" .+$", "")
