In every Java program, we have declared the main method static. It is because to run the program the JVM should be able to invoke the main method during the initial phase where no objects exist in the memory. Example 1: Java static and non-static MethodsIn Java, a method that calls itself is known as a recursive method. And, this process is known as recursion. A physical world example would be to place two parallel mirrors facing each other. Any object in between them would be reflected recursively.Output: varuaS tekaS.
