7 easy java questions! Thanks to whomever helps me!!

1. Identify the false statement.

a. If a loop's tested Boolean expression is true, a block of statements called the loop body executes before the Boolean expression is evaluated again.

b. A loop is a structure that allows repeated execution of a block of statements as long as a tested expression is true.

c. When the Boolean evaluation tested in a loop becomes false, the loop body executes one last time.

2. Identify the false statement.

a. In an indefinite loop, you don't know how many times the loop will occur.

b. A well-written while loop contains an initialized loop control variable that is tested in the while expression and then altered in the loop body.

c. A finite loop executes a specific number of times; an indefinite loop is one that never ends.

3. Identify the false statement.

a. Assume that x = 4 and y = 5. The value of y += x is 9.

b. Assume that x = 4 and y = 5. The value of ++y + ++x is 11.

c. Assume that x = 4 and y = 5. The value of y == x++ is true.

4. Identify the false statement.

a. The body of a for loop might never execute.

b. A for loop always must contain two semicolons within its parentheses.

c. Within the parentheses of a for loop, the last section must alter the loop control variable.

5. Identify the false statement.

a. When the body of a dowhile loop contains a single statement, you do not need to use curly braces to block the statement.

b. The dowhile loop checks the value of the loop control variable at the top of the loop prior to loop execution.

c. When the statements in a loop body must execute at least one time, it is convenient to use a dowhile loop.

6. Identify the false statement.

a. An inner nested loop must be entirely contained within its outer loop.

b. You can place a while loop within a while loop or a for loop within a for loop, but you cannot mix loop types.

c. The body of the following loop executes 20 times: for(int x = 0; x < 4; ++x) for(int y = 0; y < 5; ++y) System.out.println("Hi");

7. Identify the false statement.

a. You can improve loop performance by making sure the loop does not include unnecessary operations in the body of the loop.

b. You can improve loop performance when two conditions must both be true by testing for the most likely occurrence first.

c. You can improve the performance of a loop by making sure the loop does not include unnecessary operations in the tested expression.
