How to read different data types?

In Java, you can read different data types using the Scanner class with specific methods for each type. Here are examples for reading int, double, and String:

import java.util.Scanner;

public class ReadDifferentDataTypes {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        // Read an integer
        System.out.print("Enter an integer: ");
        int number = scanner.nextInt();

        // Read a double
        System.out.print("Enter a decimal number: ");
        double decimal = scanner.nextDouble();

        // Read a string
        scanner.nextLine(); // Consume the newline left-over
        System.out.print("Enter your name: ");
        String name = scanner.nextLine();

        // Display the inputs
        System.out.println("Integer: " + number);
        System.out.println("Decimal: " + decimal);
        System.out.println("Name: " + name);

        scanner.close();
    }
}

Explanation:

• scanner.nextInt(); reads an integer value.
• scanner.nextDouble(); reads a double (decimal) value.
• scanner.nextLine(); reads a line of text (string). Note that we call scanner.nextLine(); after reading a number to consume the leftover newline character.

This way, you can read various data types from user input in Java. Let me know if you need further assistance!
