1Z0-811 1Z0-811 Java Operators and Control Flow 1

Question 1

What is the result of the expression `10 % 3` in Java?

Accepted Answer

1

Answer

The `%` operator returns the remainder of integer division, so 10 divided by 3 leaves a remainder of 1.

Question 2

Which operator is used for short-circuit logical AND in Java?

Accepted Answer

&&

Answer

The `&&` operator performs a short-circuit logical AND, meaning the second operand is not evaluated if the first is false.

Question 3

What is the output of `int x = 5; System.out.println(x++);`?

Accepted Answer

5

Answer

The post-increment operator `x++` returns the current value of x (5) before incrementing it to 6.

Question 4

Which control flow statement is used to exit the current iteration of a loop and proceed to the next?

Accepted Answer

continue

Answer

The `continue` statement skips the rest of the current loop iteration and jumps to the loop condition check for the next iteration.

Question 5

What is the result of `true || false && false` in Java?

Accepted Answer

true

Answer

Due to operator precedence, `&&` is evaluated before `||`, so the expression becomes `true || (false && false)` = `true || false` = `true`.
