How to copy the characters of a given String into an Array of characters using the Java getChars() method
In this video, we will talk about the getChars() method, which is useful when copying characters of a given String into an Array of characters.
Now, let’s take an example to show you how this method works
String str = “I love programming”;
We will need an Array in which we will store all the copied characters
char[] copied_characters = new char[10];
Now, let’s call out method
This method takes four parameters:
• the first parameter is of type integer and it represents the index of the first character in the String to copy
• the second parameter is of type integer and it represents the index of the last character in the String to copy
• the third parameter represents the array of characters in which the characters from the String get copied
• the fourth parameter represents the index position in the Array from where the copied characters will be pushed into array
str.getChars(5 , 9 , copied_characters , 0);
Let’s print the content of our array
for(char content : copied_characters) {
System.out.println(content);
}
Let’s also note that, if
• The first parameter if less than zero, the method will throw an exception
• The second parameter is greater than the length of the String, the method will throw an exception
• The third parameter is less than zero, the method will throw an exception
• The fourth parameter is greater than the length of the Array, the method will throw an exception

How to install Bootstrap ?
There are multiple ways to install Bootstrap
Npm
RubyGems
Composer
NuGet
But in this video, I will show you how to install it the classical way
Start by downloading the Bootstrap V.5 zip file
Once downloaded, unzip it and rename it if you wish
Next, open the folder in your Visual Studio Code editor by right-clicking and click on Open with VS Code
Once your Visual Studio code is open create an index.html file
Click on the New File button and type in index.html
Open the index.html file
Type the exclamation mark! then hit the Tab key
Change the title of the web page to Web Project - Bootstrap V.5
Now, we have to link our web page to the Bootstrap CSS
Next in the body of the web page, we need to add the newest version of popper.js
Go to google and type Newest version of popper.js
Click on the link Popper (v2.x)
Copy and paste the CDN link
And we are also going to link the JavaScript part of bootstrap bootstrap.js
Now, let’s try to see if everything is working properly
I will first add a tag in the body
Save the file and then open your index.html file in the browser
There it is, the default bootstrap font is picking
To verify that, right-click and Inspect the page
Or, I can add a predefined bootstrap class the will change the background color of the text
Refresh
There it is, our bootstrap installation is working
