I'm only 11, but I know html, CSS, javascript, and C#.
I was wondering, if Java is like C#, as it looks pretty similar, I could just start coding :)!

i don't know much about c#, but looking at the syntax, it is much more like c++ than java, it looks like many of the keywords are different, converting to and from languages, if you know the ideas behind it and the concepts, it us usually a matter of learning the new keywords

Java does not have the delegate system or unsafe context that C# has to offer. Everything done in Java is done within safe context - so there is no pointer arithmetic in Java.
There are also no partial classes in Java, like there are in C#, so you can't have overlapping classes [defined within the same package].
If you really have the need to store an array of methods, you will sadly have to use the Reflection API--
import java.lang.reflect.*;
import java.util.Random;
public class MethodTest{
Method methods[];
public MethodTest(){
Class c = this.getClass(); // assigning the Class of this object (class) to c
methods = c.getDeclaredMethods(); // returning the methods within this class and assigning them to methods
}
public void methodOne(){
System.out.println("Method number 1");
}
public void methodTwo(){
System.out.println("Method number 2");
}
public void methodThree(){
System.out.println("Method number 3");
}
public static void main(String... args){
Random rgen = new Random(); // for randomness
MethodTest mt = new MethodTest();
while(true){
try{
mt.methods[rgen.nextInt(3) + 1].invoke((MethodTest)mt); // not quite as convenient as C# Delegation, is it?
Thread.sleep(rgen.nextInt(2500));
}catch(Exception e){e.printStackTrace();}
}
}
}
--but it's not a good idea. Apparently there's a cost of additional overhead when using reflection calls.
