Find a text in a file and write a word following this word

[lemontree45]

Hi all,

I have a text file where I have to find a particular word1 and then add a word2 soon after this word. By using FileWriter I could do only writing to a file. But how to find the word and also followed by writing into it. Please help.

Thanks & Regards

But how to find the word and also followed by writing into it.

What is the program supposed to do? Insert a String into a text file at a specific location?
You need to read the file and copy its contents to a temp file, when at the location, write out the new word, then continue reading and copying the rest of the file. When finished, rename the original file or delete it and rename the temp file to the original name

Thank you for the help. I have already got the index number, where I have to enter the word. which command should I use to insert a word at that index number. I couldn't find one.

I look forward to a reply.

Thanks and regards

which command should I use to insert a word at that index number.

Sorry, I don't understand. Java doesn't have any commands.
What is the index number? Are you trying to insert an element into an array?
