i need to write this In Java, how do I do it ?

1) WITHIN LABTIME: Write a method called reverse that takes an array of integers as an input and returns the same values in reverse order as the output. Test your method in the main. 2) WITHIN LABTIME: Write a method called myATOAL that turns your array into an ArrayList (without using built-in Java support for this). Test your method in the main. 3) Write a method called symmmetricArray, it should take an array of integers as input and check if the array is symmetric or not, returning TRUE if it is and FALSE, if it isn't. For example: 5 6 5 4 3 Is not symmetric. While: 2. 1 3 1 2 IS SYMMETRIC
