how get maximum value ?

You already know how to read a text file from your previous post:

And from that same thread (reply #3), you already know how to split a line of text into different parts.

When you have split the line in two parts, convert the second part to a number. Have a look at java.lang.Integer's parseInt(...) method to convert a String to a number:

Now you can keep track of the largest number.

Initialize a variable called currentMax and assign it to the first value in your text file. Now loop through the entire text file and if you encounter a number that is larger than currentMax, let that value be the new currentMax.
