CodingBat - Java - Array1 - firstLast6 - how to call the boolean method with an array as a parameter

I hope all is well. I've recently solved an algorithm in Coding Bat (Java - Array1 - firstLast6):

Problem

*Given an array of ints, return true if 6 appears as either the first or last element in the array. The array will be length 1 or more.

firstLast6([1, 2, 6]) → true

firstLast6([6, 1, 2, 3]) → true

firstLast6([13, 6, 1, 2, 3]) → false*

My Solution

public boolean firstLast6(int[] nums) { if ( (nums[0] == 6) || (nums[nums.length - 1]) == 6 ) { return true; } return false; } 

This is the correct solution. However, it's one thing to solve the problem in Coding Bat, but I want to be able to call this boolean method in my VS Code editor in the main method. My research thus hasn't produced a solid answer to my question.

In the main method:

1. Boolean method call: How would you call the boolean method that has an array (nums) as a parameter? I'm stuck on the syntax for this part.

2. Print out statement: Using "System.out.println()" print out the true or false result?

VS Code - Full Layout

public class ReturnStatements { public static void main(String[] args) { // Method call // Print out statement outputing true or false. } public static boolean firstLast6(int[] nums) { if ( nums[0] == 6 || nums[nums.length - 1] == 6 ) { return true; } return false; } }

You can do:

public static void main(String[] args) { System.out.println(fistLast6(new int[] {1, 2, 6})); } 

And @thinkgruen's suggestion:

public static boolean firstLast6(int[] nums) { return nums[0] == 6 || nums[nums.length - 1] == 6; } 

public class ReturnStatements { public static void main(String[] args) { // Method call boolean toFirstLast6 = firstLast6(new int[] {1, 2, 6}); // Print out statement outputing true or false System.out.println(toFirstLast6); } public static boolean firstLast6(int[] nums) { if ( nums[0] == 6 || nums[nums.length - 1] == 6 ) { return true; } return false; } }
