# 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!" );
else
System.out.println("Out of range." );
}
}
```

### QUESTION 9:

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

• `weight` must be equal or greater than 136
• `weight` must be less than or equal to 147
