Java string split with Multiple Characters Delimiter

Question

I have a very complicated output from a function, which i need to use specific word from it.

For example , my output is:

 oracle   11257     1  0 14:01 ?        00:00:00 ora_pmon_sas

I need to get just " sas " word, which is next to " ora_pmon_ "

Another example:

oracle   6187     1  0 13:41 ?        00:00:00 ora_pmon_db2

I need to get " db2 ". So what should be my expression?

JAVA code:

insArray=line.split("what will be between these quotes?");  

Answer 1

你可以做

String sub = s.substring(s.indexOf("ora_pmon_") + 9);

Answer 2

How about this one?

string = string.replaceAll(".*?ora_pmon_", "");

If you want multiple words in place of ora , then it will be

string = string.replaceAll(".*?(ora|kf|asm)_pmon_", "");

Answer 3

You can simply use String#substring(int i) combined with String#lastIndexOf(char ch)

For example:

String result = input.substring(input.lastIndexOf('_') + 1)
