Declaring an array in Java is pretty straightforward! You use the type of data the array will hold, followed by square brackets, and then the array name. For example, int[] myArray; declares an integer array. If you're ready to initialize it right away, you could do int[] myArray = new int[10]; to create an array with 10 integers. What kind of project are you working on that involves arrays? Or perhaps you're learning Java and have questions around it?
