Method Detail

isBetween

public static boolean isBetween(int min,
                                int max,
                                int value)

Returns true if value is strictly greater than min and strictly less than max, and false otherwise.

Parameters:

min - a minimum value

max - a maximum value

value - a value to check

Returns:

true if value is strictly greater than min and strictly less than max, and false otherwise

min2

public static int min2(List<Integer> t)

Given a list containing exactly 2 integers, returns the smaller of the two integers. The list t is not modified by this method. For example:

 t            Test2F.min2(t)
 ---------------------------
 [-5, 9]      -5
 [3, 3]        3
 [12, 6]       6
 

Parameters:

t - a list containing exactly 2 integers

Returns:

the minimum of the two values in t

Throws:

IllegalArgumentException - if the list does not contain exactly 2 integers

Precondition:

t is not null

countGreaterThan

public static int countGreaterThan(List<Integer> t,
                                   int value)

Counts the number of elements in t that are greater than value. The list t is not modified by this method. For example, if value == 3 then:

 t                      Test2F.countGreaterThan(t, 3)
 ----------------------------------------------------
 []                     0
 [-5]                   0
 [3, 4]                 1
 [12, 6, 8, 2, 2, 2]    3
 

Parameters:

t - a list

value - a value

Returns:

number of elements in t that are greater than value

Precondition:

t is not null

removeDigits

public static int removeDigits(int aNumber,
                               int n)

Returns the int value equal to the value obtained by removing n digits from the the end of aNumber. The method will never remove all of the digits of aNumber. If n is greater than the number of digits in aNumber then the first digit of aNumber is returned. For example:

 aNumber    n     Test2F.removeDigits(aNumber, n)
 ------------------------------------------------ 
  1         0      1 
  2         1      2
  87        1      8 
  100353    3      100 
 -9325256   5     -93
 -9325256   999   -9
 

Parameters:

aNumber - a number

n - the number of digits to remove from the end of aNumber

Returns:

the number equal to removing n digits from the end of aNumber, or the first digit of aNumber if n is greater than or equal to the number of digits in aNumber
