A good answer might be:

There are two paths through this chart.

Decisions

The "windshield wiper" decision is a two-way decision (sometimes called a "binary" decision.) It seems small, but in programs complicated decisions are made of many small decisions. Here is a program (suitable for "copy-paste-and-run") that includes a binary decision.

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

    String inData;
    int    num;

    System.out.println("Enter an integer:");
    inData = stdin.readLine();
    num    = Integer.parseInt( inData );     // convert inData to int
    
    if ( num < 0 )   // is num less than zero?               
      System.out.println("The number " + num + " is negative");  // true-branch
    else
      System.out.println("The number " + num + " is positive");  // false-branch
    
    System.out.println("Good-bye for now");    // always executed
  }
}

The words if and else are markers that divide the decision into two sections. The else divides the "true branch" from the "false branch".

Notice that a two-way decision is like picking which of two roads to take to the same destination. The fork in the road is the if statement, and the two roads come together just after the false-branch.

QUESTION 3:

The user runs the program and enters "12". What will the program print?
