Question

import java.util.Scanner;

public class InRange {
private int min;
private int max;

public InRange(int initialMin, int initialMax) {
min = initialMin;
max = initialMax;
}

// You need to write two instance methods:
// 1.) A method named inRange, which takes an int.
// This returns true if the int is within the given range
// (inclusive), else false.
//
// 2.) A method named outOfRange which takes an int.
// This returns false if the int is within the given range
// (inclusive), else true. This method calls inRange.
//
// outOfRange always does the exact opposite of inRange.
// FOR FULL CREDIT, outOfRange MUST CALL inRange and negate the result!
//
// TODO - write your code below this comment.
  
public boolean inRange(int a){
return a >= min && a <= max;
}
  
public boolean outOfRange(int a){
return !inRange(a);
}
  
  
// Do not Modify main()
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Low end of range: ");
int min = input.nextInt();
System.out.print("High end of range: ");
int max = input.nextInt();
System.out.print("Number: ");
int num = input.nextInt();
InRange range = new InRange(min, max);
  
System.out.println("In range: " + range.inRange(num));
System.out.println("Out of range: " + range.outOfRange(num));
}
}

NEED HELP WITH TEST

import static org.junit.Assert.assertEquals;
import org.junit.Test;

public class InRangeTest {
    @Test
    public void testInRangeAtLowEndOfRange() {
        InRange range = new InRange(5, 10);
        assertEquals(true, range.inRange(5));

        // TODO: add an assertEquals statement below which
        // checks that InRange.outOfRange returns false for the
        // same parameter above.
    }

    @Test
