int y = 3;
double z = x / y + 0.5;

What is the result of the following expression in Java?

int result = 3 + 4 * 2 - 10 / 4;

What is the output of the following code?

int x = Integer.MAX_VALUE;
x = x + 1;
System.out.println(x > 0);

After the following code executes, what is the value of n?

double d = 7.9;
int n = (int) d % 3;

Which of the following correctly declares a boolean variable and assigns it the result of a comparison?

// Option A
boolean result = (7 > 3);

// Option B
Boolean result = 7 > 3;

// Option C
bool result = 7 > 3;

// Option D
boolean result = "7 > 3";
