Suppose income is 4001, what is the output of the following code:
if (income > 3000) {

}
else if (income > 4000) {
 System.out.println("Income is greater than 4000");
}

• no output
  No output
• Income is greater than 3000 
• Income is greater than 3000 followed by Income is greater than 4000
• Income is greater than 4000 followed by Income is greater than 3000

Suppose you write the code to display "Cannot get a driver's license" if age is less than 16 and

Which of the following code is the best?

• if (age < 16) 
   System.out.println("Cannot get a driver's license");
  if (age >= 16) 
   System.out.println("Can get a driver's license");
• if (age < 16) 
   System.out.println("Cannot get a driver's license");
  else 
   System.out.println("Can get a driver's license");
• if (age < 16) 
   System.out.println("Cannot get a driver's license");
  else if (age >= 16) 
   System.out.println("Can get a driver's license");
• if (age < 16) 
   System.out.println("Cannot get a driver's license");
  else if (age > 16) 
   System.out.println("Can get a driver's license");
  else if (age == 16) 
   System.out.println("Can get a driver's license");
