What does this code snippet print if int score = 75;?

if (score >= 90)

{ System.out.println("Grade A");}

else if (score >= 80)

{ System.out.println("Grade B");}

else if (score >= 70)

{System.out.println("Grade C");}

else

{System.out.println("Grade D or below");}

• Grade A

Which of the following correctly describes nested if statements?

• if statements placed one after another.

• An if statement with no else condition.

• Multiple else statements in a row.

What will this nested if statement output if int age = 20; boolean member = true;?

if (member) {

if (age >= 18)

{ System.out.println("Eligible for premium membership"); }

}

else { System.out.println("Not a member");}

• Eligible for premium membership

• Eligible for youth membership

• Not a member

• Error

In the code below, what will be the output if int x = 10, y = 5;?

if (x > y && y > 0) {

}

• x is greater and y is positive

• Conditions not met

• Error

• y is positive

Which of the following is the correct syntax for an if-else statement?
