import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String numStr = input.nextLine();
double num;
try{
num = Double.parseDouble(numStr);
}
catch(NumberFormatException e){
num = 0;
System.out.println("Value entered cannot be converted to a floating point number.");
}
}
}

Explanation:

The solution code is written in Java.

Firstly, we create a Scanner object and prompt user to input a number (Line 5-6). Next, we create a try -catch block and place the parseDouble inside the try block. If the input is invalid (e.g. "abc"), a NumberFormatException error will be thrown and captured and set the num to 0 and display the error message (Line 11 - 13).
