How to ask for an array and how to save the values

Question

I'm supposed to be learning the differences between a linear search and a binary search, and the assignment is to have a user input an array and search through the array for a given number using both searches. My problem is that I know how to ask them how long they want their array to be, but I don't know how to call the getArray() method to actually ask for the contents of the array.
My code is as follows:
import java.util.Scanner;
import java.util.ArrayList;
public class Main
    private static Scanner input = new Scanner(System.in);
    public static void main (String args[])
        //creates ArrayList
        int List[];
        System.out.println("How long would you like the array to be?");
        int arrayLength = input.nextInt();
        //Initializes array list
        List = new int [arrayLength];
        System.out.println("Please enter the first value of the array");
    public static void getArray(int List[], int arrayLength)
        for(int i=0; i < arrayLength; i++) {
             System.out.println("Enter the next value for array");
             List[i] = input.nextInt();
     public static void printArray(int List[])
         for(int i=0; i < List.length; i++)
             System.out.print(List[i] + " ");
public class search
    public static int binarySearch(int anArray[], int first, int last, int value)
        int index;
        if(first > last) {
            index = -1;
        else {
            int mid = (first + last)/2;
            if(value == anArray[mid]) {
                index = mid; //value found at anArray[mid]
            else if(value < anArray[mid]) {
                //point X
                index = binarySearch(anArray, first, mid-1, value);
            else {
                //point Y
                index = binarySearch(anArray, mid+1, last, value);
            } //end if
        } //end if
        return index;
    //Iterative linear search
    public int linearSearch(int a[], int valueToFind)
        //valueToFind is the number that will be found
        //The function returns the position of the value if found
        //The function returns -1 if valueToFind was not found
        for (int i=0; i<a.length; i++) {
            if (valueToFind == a) {
return i;
return -1;

I made the changes. Two more questions.
1.) Just for curiosity, how would I have referenced those methods (called them)?
2.) How do I call the searches?
import java.util.Scanner;
import java.util.ArrayList;
public class Main
    private static Scanner input = new Scanner(System.in);
    public static void main (String args[])
        //creates ArrayList
        int List[];
        System.out.println("How many values would you like the array to have?");
        int arrayLength = input.nextInt();
        //Initializes array list
        List = new int [arrayLength];
        //Collects the array information
        for(int i=0; i < arrayLength; i++) {
             System.out.println("Enter a value for array");
             List[i] = input.nextInt(); 
        //Prints the array
        System.out.print("Array: ");
        for(int i=0; i < List.length; i++)
             System.out.print(List[i] + " ");
        //Asks for the value to be searched for
        System.out.println("What value would you like to search for?");
        int temp = input.nextInt();
        System.out.println(search.binarySearch()); //not working
}
