Analyze the following code: public class Test { private int t; public static void main(String[] args) { int x; System.out.println(t); } } The variable t is private and therefore cannot be accessed in the main method. The program compiles and runs fine. t is non-static and it cannot be referenced in a static context in the main method. The variablet is not initialized and therefore causes errors. The variable x is not initialized and therefore causes errors.
