Thread: Character string extraction from a text file

Hi,

Please I am a beginner in java, I want to extract information from a text file. is the following:
============================================

From: 55555565
From_SMSC: 78987555
Sent: 00-02-21 22:26:23
Received: 00-02-21 22:26:29
Subject: modem1
Alphabet: ISO
UDH: false

pr2

============================================

I want to extract the first line which is exactly the number " 55555565 " and the last line is "pr2".

for now I just use the code that allows me to extract only the last line"pr2".

++++++++++++++++++++++++++++++++++++++++++++

Scanner scanner = new Scanner(new File(/home/Desktop/ivw.txt));
String line = null;
while (scanner.hasNextLine()) {
line = scanner.nextLine();
}
 
readSMS=line;
scanner.close();

++++++++++++++++++++++++++++++++++++++++++++

I want to retrieve information both the first line and the last line so that I can put each in a variable.

thank you for your help

hi,

the problem is that I do not know how to specify the first line.
