A good answer might be:

Enter an integer:
17
The number 17 is positive
positive numbers are greater or equal to zero
Good-bye for now

The false block was executed because the answer to the question (num < 0) was false. The false block consists of two statements.

Outline of a Two-way Decision

Here is how an outline of how make a two-way decision:

... statements done before the decision

if ( condition )
    ....  // true branch

else
    ....  // false branch

... statements done after the branch comes back together

Here are some details:

The condition evaluates to true or false, often by comparing variables and values.
The else divides the true branch from the false branch.
The statement after the false branch (or false block) always will be executed.
A block consists of several statements inside a pair of braces, { and }.
The true branch can be a block.
The false branch can be a block.
There can be as many statements in a block as you need.
When a block is chosen for execution, the statements in it are executed one by one.

The condition can compare what is held in a variable to other values. You can use the comparisons: <, >, and so on. (More about these later.) The first statement after the false branch will be executed no matter which branch is chosen. The if-else is like a fork in the road, but the road always comes together again.

QUESTION 7:

Do you believe that the following section of a program is correct?

if ( num < 0 )
    System.out.println("The number " + num + " is negative");   
else
    System.out.println("The number " + num + " is positive");  
    System.out.print  ("positive numbers are greater ");  
    System.out.println("or equal to zero ");    
System.out.println("Good-bye for now");
