Program:

import java.util.Scanner;

public class InputBaseTypesExample {

    public static void inputAllBaseTypes() {
        Scanner scanner = new Scanner(System.in);

        // Input integer
        System.out.print("Enter an integer: ");
        int intValue = scanner.nextInt();
        System.out.println("Integer Value: " + intValue);

        // Input double
        System.out.print("Enter a double: ");
        double doubleValue = scanner.nextDouble();
        System.out.println("Double Value: " + doubleValue);

        // Input char
        System.out.print("Enter a character: ");
        char charValue = scanner.next().charAt(0);
        System.out.println("Character Value: " + charValue);

        // Input boolean
        System.out.print("Enter a boolean (true/false): ");
        boolean booleanValue = scanner.nextBoolean();
        System.out.println("Boolean Value: " + booleanValue);

        // Input string
        System.out.print("Enter a string: ");
        String stringValue = scanner.next();
        System.out.println("String Value: " + stringValue);
    }

    public static void main(String[] args) {
        inputAllBaseTypes();
    }
}

Output:

Enter an integer: 12
Integer Value: 12
Enter a double: 44.5678
Double Value: 44.5678
Enter a character: r
Character Value: r
Enter a boolean (true/false): true
Boolean Value: true
Enter a string: Ansari
String Value: Ansari
