Hey guys Im having trouble with a few simple functions i need to do for my class in Java... Any help would be greatly appreciated ...

class BetterLoop

{

public static boolean contains(int [] values, int v)

{

/* TO DO: if value v is in the array, return true.

If not, return false. Use a "foreach" loop.

*/

return true; // A bit optimistic, but a real boolean value.

}

}

import java.util.LinkedList;
	import java.util.List;
	import java.util.Map;
	class ExampleMap
	{
	public static List highEnrollmentStudents(
	Map> courseListsByStudentName, int unitThreshold)
	{
	List overEnrolledStudents = new LinkedList<>();
	/*
	Build a list of the names of students currently enrolled
	in a number of units strictly greater than the unitThreshold.
	*/
	return overEnrolledStudents;
	}
	}

class SimpleArray
	{
	public static int [] squareAll(int values[])
	{
	/* TO DO: This size is not right. Fix it to work with any
	input array. The length of an array is accessible through
	an array's length field (e.g., values.length).
	*/
	int [] newValues = new int[1]; // This allocates an array of integers.
	/* TO DO: The output array, newValues, should hold as
	its elements the square of the corresponding element
	in the input array.
	Write a loop to compute the square of each element from the
	input array and to place the result into the output array.
	*/
	return newValues;
	}
	}
