How to extract some text from a string in java

Question

I have string:

Adding offert to database.

number of agreement: 98393553553
number of accounting: 1242422222222222224242
Agreement in step: Accounting

How to extract text: 98393553553 (text has always the same number of characters - 11 characters) using Java. Text before: 98393553553 it can be different (sometimes).

Your question doesn't show any effort of neither you trying to solve your problem on your own; nor you checking stack overflow for this question. Do you really assume that you are the very first person who is asking here how to parse strings in Java? — GhostCat, Apr 22 '15 at 12:16

Try using String.split() with the delimiter :, and String.substring() on index 1 of the String[] obtained from the earlier String.split().

Good effort but in theory that will still return `98393553553 number of accounting` ;) – Ceiling Gecko Apr 22 '15 at 12:20

That's why I said use `String.substring()` as he said the number is of length 11. – M. Shaw Apr 22 '15 at 12:22

You may use a regular expression matcher for this:

import java.util.regex.Matcher;
import java.util.regex.Pattern;

  String line = .........; //your input line
  String pattern = "number of agreement:\\s*(\\d+)";

  // Create a Pattern object
  Pattern r = Pattern.compile(pattern);

  // Now create matcher object.
  Matcher m = r.matcher(line);
  if (m.find( )) {
     System.out.println("Number of agreement: " + m.group(0) );
  } else {
     System.out.println("Number of agreement not found");
  }

You can use String.split() and store it into a String Array. Then finally extract whatever you want from the array.
