How heavy is the boxer? 140 In range!
The and-operator gives true because both sides are true:
weight >= 136 && weight <= 147
 140   >= 136 &&   140  <= 147
 ------------      -----------
    true               true

             true
An unmarried taxpayer in the US with an income of $24,000 up to $58,150 (inclusive) falls into the 28% "tax bracket." Here is a program that tests if a taxpayer falls into this bracket.
// IRS Weigh-in
//
//   Income between $24000 and $58150 inclusive
//
import java.io.*;
class TaxGouge
{
  public static void main (String[] args) throws IOException
  { 
    BufferedReader stdin = 
        new BufferedReader ( new InputStreamReader( System.in ) );
 
    String inData;
    int    income; 
    // get the income
    System.out.println("What is your income?");
    inData   = stdin.readLine();
    income   = Integer.parseInt( inData ); 
    // check that the income is within range for the 28% bracket
    if ( _______________________ )
      System.out.println("In the 28% bracket." );
    else
      System.out.println("Time for an audit!" );
  }
}
