Answer 1

class Main { public static void main(String[] args) { System.out.println("John Nash"); // pur your name here } }	Output: John Nash
class Main { public static void main(String[] args) { // declaring variables double a = 1.5; double b = 2.5;    // performing addition operation double c = a+b;    // printing output System.out.println(c); } }	Output: 4.0
import java.util.Scanner; class Main { public static void main(String[] args) { // declaring a scanner variable Scanner sc = new Scanner(System.in);    // Prompting for user input System.out.print("Enter a number: ");    // taking user input int a = sc.nextInt();    // printing output System.out.println("You entered "+a); } }	Sample Output Enter a number: 9 You entered 9
import java.util.Scanner; class Main { public static void main(String[] args) { // declaring a scanner variable Scanner sc = new Scanner(System.in);    // Prompting for user input System.out.print("Enter a number: "); int intc = sc.nextInt();    System.out.print("Enter a number: "); int intd = sc.nextInt();    // declaring variables double a = 1.5; double b = 2.0;    // performing addition operation double c = a+b+intc+intd;    // printing output System.out.println(c); } }	SAMPLE OUTPUT Enter a number: 2 Enter a number: 3 8.5
