A good answer might be:

    if ( num < 0 )
        System.out.println("The number " + num + " is negative");  // true-branch
    else
    {
        System.out.println("The number " + num + " is positive");  // false-branch
        System.out.print  ("positive numbers are greater ");       // false-branch   
        System.out.println("or equal to zero ");                   // false-branch
    }                      
    System.out.println("Good-by for now");                         // always executed

Notice that in this program that the true branch has one statement, which is not a block, and that the false branch has one statement, which is a block (and as a block contains three statements.)

Practice

At a movie theater box office a person less than age 17 is charged the "child rate". Otherwise a person is charged "adult rate." Here is a partially complete program that does this: 

import java.io.*;
class BoxOffice
{
  public static void main (String[] args) throws IOException
  {
     BufferedReader stdin = 
        new BufferedReader ( new InputStreamReader( System.in ) );

    String inData;
    int    age;

    System.out.println("Enter your age:");
    inData = stdin.readLine();
    age    = Integer.parseInt( inData );     // convert inData to int

    if ( __________________  )
    {
      System.out.println("Child rate.");   
    } 
    else
    {
      System.out.println("Adult rate.");   
    }
    System.out.println("Enjoy the show.");    // always executed
  }
}

In this program, the true branch and the false branch are both blocks. Each block has only one statement inside of it, but this is OK. All you need to do is complete the blank so the program picks the correct block for the age that was input.

QUESTION 9:

Fill in the blank of the program. You might wish to make a copy of the program in NotePad, make your proposed correction, and run it to see if it works as you think.
