search for string in line

I have problem dealing with a string in a line, For example i have the following lines in a .txt file:

ussdserver link from host /127.0.0.1:38978(account smpp34) is up|smpp34|2012-10-28 17:02:19
ussdserver link from host localhost/127.0.0.1:8088(account callme) is up|callme|2012-10-28 17:02:20

I need my code to get the word after "account" (in the first line it's smpp34) and the word "up" (after the "is" word).

I thought about using String.charAt() method but it doesn't work here because the words that I need can be in different places, as shown in the example above.

Try RegEx like this.

  Pattern pattern = Pattern.compile(".*account\\s([^\\s]*)\\)\\sis\\s([^|]*)|.*");
  Matcher matcher = pattern.matcher("ussdserver link from host /127.0.0.1:38978(account smpp34) is up|smpp34|2012-10-28 17:02:19");
  while (matcher.find()) {
    System.out.println(matcher.group(1));//will give you 'smpp34'
    System.out.println(matcher.group(2));//will give you 'up'
    return;
  }

Yeah its best to use regex in this sort of cases..But a simpler method can be used specifically for above case. Simply Try splitting from ) and then read till length of string-5 to length will give you the first word and try similar for second word..

IF and Only if the String pattern above never changes..Else will recommend using regex..

Try using following methods form String class.

String inputStr = "ussdserver link from host /127.0.0.1:38978(account smpp34) is up|smpp34|2012-10-28 17:02:19";
int index1 = inputStr.indexOf("account");
int index2 = inputStr.indexOf(')',index1);
String accountName = inputStr.substring(index1+8,index2); // you get smpp34

index1 = inputStr.indexOf("|");
index2 = inputStr.lastIndexOf(' ', index1);
String state = inputStr.substring(index2+1, index1) // you get up
