What will this output?System.out.println(4 + 5 * 2);

• 14

• None of the above

Which is the correct boolean expression which gives the following meaning:The value of x is greater than 1000 and x is smaller or equal to 2000

• X >= 1000 && x

• X > 1000 && x < 2000

• X < 1000 && x >= 2000

• X > 1000 && x

• None of the above

What will be the output of the following programclass A{   public static void main(String[] args)   {      System.out.println(getWelcomeMessage());   }   static String getWelcomeMessage()   {      return "Welcome!!!";   }}

• GetWelcomeMessage()

• GetWelcomeMessage

• Will not compile

Will this compile?class A{    System.out.println(20 * 10);}

• Yes

• No

What will this output?System.out.println(5/2);

• 2

• 2.5

• Some kind of error

• 3

Will this compile?class B{   public static void main(String[] args)   {      Scanner sc = new Scanner(System.in);   }}

• Yes

• No

Rewrite this as a for loopint i = 0;while (i < 10){   System.out.println(i);   i++;}

Write a program that will ask the user to start entering numbers. When he enters the number 0, you will show to him the sum of all the numbers he has entered.
