There is no global variable in Java. However, we have a static keyword that we can use to define a global variable by doing something like the below:
public class A { public static String var1 = "Oraask"; public static int var2 = 37; }But be careful because if this class gets unloaded, you will end up with an undefined null error that is difficult to catch.
