Taking input from the user in Java is straightforward with the Scanner class. This example demonstrates how to use Scanner to read user input and display it. By importing java.util.Scanner, you can create a Scanner object to read data from the console. This method is useful for interactive applications, enabling users to provide necessary data during runtime. Whether it's for a simple calculator or a complex system, understanding user input handling is fundamental in Java programming.

Note:
- Please turn on Interactive Mode so that the program can work properly in the simulation.
- In case of any internet error message in the output, just click on the execute again.
- Please make sure to have stable internet.
- in case 400Error refresh the page and check your internet connection.
Example 1:
This example reads a string input from the user. scanner.nextLine() captures the entire line of input until the user presses Enter. The entered name is then printed with a greeting.
Example 2:
This example reads an integer input. scanner.nextInt() is used to capture the user's age, which is then printed.
Example 3:
This example reads a floating-point number using scanner.nextFloat(). The entered number is then printed.
Example 4:
This example captures a double value with scanner.nextDouble(). The entered value is then displayed.
Example 5:
To read a single character, this example uses scanner.next().charAt(0). It reads the first character of the input string.
This example demonstrates reading multiple inputs of different types. It captures a string for the name, an integer for the age, and a double for the salary. The values are then printed in a formatted message.
These examples cover basic user input scenarios in Java, providing a foundation for handling different data types entered by the user.
