Range Testing

Frequently you need to test if a number is within a certain range.

A welter weight boxer must weight between 136 and 147 pounds. A boxer's weight is tested before each fight to be sure that he is within his weight category. Here is a program that checks if a welter weight boxer's weight is within range:

// Ringside Weigh-in
// Boxer must weigh between 136 and 147 pounds
import java.util.Scanner;

public class Ringside
  public static void main (String[] args)  
    Scanner scan = new Scanner( System.in );
    int weight; 

    // get the weight
    System.out.print("How heavy is the boxer? ");
    weight = scan.nextInt();

    // check that the weight is within range
    if (  )
      System.out.println("In range!" );
      System.out.println("Out of range." );


Fill the blank so that weight is tested in two ways:
