it should not have any arraylist and im using eclipse program to write this code

Modifier and TypeMethodDescriptionstatic int$[]$filter$($int$[]$array$,$ int$$lowerLimit$,$ int$$upperLimit$)$

Returns a new array with values in array that exists in the range defined by lowerLimit $($inclusive$)$ and upperLimit $($inclusive$).$

static java.lang.StringgetArrayString$($int$[]$array$,$ char$$separator$)$

Return a string where each array entry $($except the last one$)$ is followed by the specified separator.

static java.lang.StringBuffer$[]$getArrayStringsLongerThan$($java$.$lang.StringBuffer$[]$array$,$ int$$length$)$

Returns a StringBuffer array with COPIES of StringBuffer objects in the array parameter that have a length greater than the length parameter.

static intgetInstances$($int$[]$array$,$ int$$lowerLimit$,$ int$$upperLimit$)$

Returns the number of values that are in the range defined by lowerLimit $($inclusive$)$ and upperLimit $($inclusive$).$

static voidrotate$($int$[]$array$,$ boolean$$leftRotation$,$ int$$positions$)$

Rotates the provided array left if leftRotation is true; right otherwise.

Method Detail

getArrayString

public static$$java$.$lang.String$$getArrayString$($int$[]$array$,$ char$$separator$)$

Return a string where each array entry $($except the last one$)$ is followed by the specified separator. An empty string will be return if the array has no elements.

Parameters:

array $-$

separator $-$

Returns:

string

Throws:

java.lang.IllegalArgumentException $-$ When a null array parameter is provided

getInstances

public static$$int$$getInstances$($int$[]$array$,$ int$$lowerLimit$,$ int$$upperLimit$)$

Returns the number of values that are in the range defined by lowerLimit $($inclusive$)$ and upperLimit $($inclusive$).$

Parameters:

array $-$

lowerLimit $-$

upperLimit $-$

Returns:

number of values in range

Throws:

java.lang.IllegalArgumentException $-$ When a null array parameter is provided

filter

public static$$int$[]$filter$($int$[]$array$,$ int$$lowerLimit$,$ int$$upperLimit$)$

Returns a new array with values in array that exists in the range defined by lowerLimit $($inclusive$)$ and upperLimit $($inclusive$).$

Parameters:

array $-$

lowerLimit $-$

upperLimit $-$

Returns:

array with values in range

Throws:

java.lang.IllegalArgumentException

$-$ When a null array parameter is provided

java.lang.IllegalArgumentException

$-$ When lowerLimit is greater than upperLimit

rotate

public static$$void$$rotate$($int$[]$array$,$ boolean$$leftRotation$,$ int$$positions$)$

Rotates the provided array left if leftRotation is true; right otherwise. The number of positions to rotate is determined by positions. For example, rotating the array $10,20,7,8$ two positions to the left will update the array to $7,8,10,20.$ Only arrays with $2$ or more elements will be rotated. Hint: adding private methods that rotate an array one position to the left and one position to the right can help.

Parameters:

array $-$

leftRotation $-$

positions $-$

Throws:

java.lang.IllegalArgumentException $-$ When a null array parameter is provided

getArrayStringsLongerThan

public static$$java$.$lang.StringBuffer$[]$getArrayStringsLongerThan$($java$.$lang.StringBuffer$[]$array$,$ int$$length$)$

Returns a StringBuffer array with COPIES of StringBuffer objects in the array parameter that have a length greater than the length parameter. If no strings are found an empty array will be returned.

Parameters:

array $-$

length $-$

Returns:

Throws:

java.lang.IllegalArgumentException $-$ When a null array parameter is provided. $1)$You may not use ArrayLists or methods from the Arrays class no array list

$2)$sysImplementation$$ A package $($folder$)$ where you will complete the $3)$implementation of the$$Utilities$$class$.$

tests$$ A package $($folder$)$ where you will find a file called$$StudentTests$.$java$$were you are expected to write tests for your program.
