Nested if Statements Practice Test

Online Shopping Cart: apply discount using nested if. Code:

boolean isMember = true;

double purchaseAmount = 120.0, discount = 0.0;

// Members get higher discount for large purchases

if (isMember) {

  discount = 0.10;

  if (purchaseAmount >= 100.0) discount = 0.20;

}

What will be the output if the input is isMember=true, purchaseAmount=120.0?

A grade program branches with nested ifs. What is grade when score=75 and extraCredit=true?

int score = 75;

boolean extraCredit = true;

String grade = "";

// Extra credit only affects borderline scores

if (score >= 80) {

    grade = "B";

} else {

    // Borderline can rise to B

    if (extraCredit && score >= 78) grade = "B";

    else grade = "C";

}
