All language subtitles for 004 JSTL even more functions

Hey there.

Welcome back, friends.

Today, we will try to check a couple of more interesting functions which are available inside a variety

of steel bags.

And these are to lower case to uppercase index of replace substring, substring before and substring

after.

Now these functions are nothing but functions which are derived from Java string functions.

And these functions work on definitely strings.

No strings.

These are very easy to understand.

And in order to save some time, I have already created the examples for all of these functions.

Now, what are functions?

Functions and methods are one and the same.

All right.

Now, moving forward, first of all, to uppercase, very definitely convert the string to uppercase

to lowercase, very definitely convert the text and to the lowercase, which is straight forward.

Then comes the index of function.

Now, first of all, we will be passing on the string and then this specific character and this function

will return the exact function not taken note of it.

A string is a character added and adding index.

It starts with zero.

So when it comes to you, in the case of state easy.

Then next would be do lie.

Right?

So it starts with zero, then one, then two.

So in the third position we have u, which has to index us two.

All right, then comes replace.

As the name suggests, we will pass on three parameters.

Firstly the string.

Then we have the segment of the string and then the replacement.

So in this case, in place of a state easy dot org is dead.

Easy would be replaced to get super easy.

Then we have the substring.

Substring again has three parameters.

Firstly the string.

Then we have the starting index, then bending index.

In here the starting index is two so the substring will start with index two, which is nothing but

you and end with index five, which isn't a thing.

But why?

So the substring would be usually why.

Then finally we have the substring before and substring after.

Substring before, as the name suggests, who will give us the substring before the segment?

Easy, which is steady.

Likewise, substring after will give us the segment which is after the segment easy, which is DART

or RG.

So these are very simple string related functions, very simple, easy to understand, easy to use.

Let us quickly try to see the output.

Here is the output and these are let me walk you through firstly uppercase.

So here is the uppercase is easy to talk than lowercase is pretty easy.

So the next output is a steady, easy, all lowercase.

Then we have the index of u, which is nothing but to as we have already discussed, index it starts

with zero, then replacing the segment steady.

Easy, but super easy.

So in here it is showing us super easy dot org if it is again.

Okay.

Cool then substring is starting with index two and ending with index five.

Which gives us substring.

You divide which is the output.

Then we have substring before easy, which is a steady perfect and then substring after easy, which

is not authority.

Here we go.

So these are the standard output from these functions.

And definitely these are useful string functions which we can use in our program.

I hope you guys understood the overall concept.

Do try to experiment and try to check all of these functions.

These are very definitely help.

All right.

So this is it for today's video.

I hope you guys enjoyed this video.

Thanks for watching.
