Practice program 63 - Write a Java program that reads an integer and checks whether it is negative, zero, or positive


            class Check_number {
                public static void main(String[] args) {
                    java.io.BufferedReader input = new java.io.BufferedReader(new java.io.InputStreamReader(System.in));
            
                    try {
                        System.out.print("Enter a number: ");
                        double number = Double.parseDouble(input.readLine());
                        StringBuffer msg = new StringBuffer("zero");
            
                        if (number > 0) {
                            msg.replace(0, msg.length(), "positive");
                        } else if (number < 0) {
                            msg.replace(0, msg.length(), "negative"); 
                        }
            
                        System.out.println("The number is " + msg);
                    } catch (java.util.InputMismatchException e) {
                        System.out.println("Invalid input. Please enter a valid numeric value.");
                    } catch (Exception e) {
                        System.out.println("Something went wrong.");
                    }
                }
            }
