Answer:
Because these subsystems interact with each other and the biosphere, they work together to influence the climate and make an affect on life all over the Earth.
Answer:
- import java.util.Scanner;
- public class TryToParseDouble {
-
- public static void main(String[] args) {
- Scanner input = new Scanner(System.in);
- double num;
-
- try{
- System.out.print("Input a number: ");
- num = Double.parseDouble(input.nextLine());
-
- }catch(NumberFormatException e){
- num = 0;
- System.out.println("Invalid input! It should be a number in double type");
- }
- System.out.println(num);
- }
- }
Explanation:
Firstly, create a Scanner object to get user input (Line 5).
Next, create a try block and prompt user to input a number and use Double.parseDouble() method to convert the input to double type in the block (Line 8-10).
Next, create a catch block to catch a NumberFormatException. In the Catch block, set the num to zero and then print out a message to inform user about the invalid input (Line 12-14).
Lastly, display the number (Line 16).
Answer:
Explanation:
In the first instance, you had a logic function, which you had derived using some sort of a truth table, then reduced it using K-maps, and finally derived the simplified logic. If you had used logic gates to implement the logic, the result would have been the fact that there were a lot of logic gates used. For example, for a function of 2 variables, we would need 4 AND gates and 1 OR gate. Thus, the resulting circuitry would have looked very complex.
Whereas, if you would use a microcontroller to implement the logic, all you need would be a piece of code to run the logic. There would either be minimum number of gates (or no gates at all, depending on the logic you wanted to implement).
Thus the microcontroller would make the circuit look a lot less complex. Making the design and texting simpler and since there are now fewer components to test. Microcontrollers is that on the same piece of silicon, you could embed a lot more complex logic or program, than using purely digital gates this is another good that comes with Microcontrollers.
