How can you convert different types of variables?

I mean as in VB where all you needed to do was put for instance:
ex:
dim x as int
x = 25
dim txt as String
txt = Str(x)
where txt would be "25"

Is there anyways easy to do this?

Variables will all convert to String with little effort. For instance, to show them on the console you can just concatenate them into a String:

int x=10;
long y=20;
char c='A';

System.out.println("VARS "+x+" "+y+" "+c);

In fact you can turn them into a String in general like that:

String txt="VARS "+x+" "+y+" "+c;


Note that for this to work, the compiler needs to know it is supposed to create a String. So to turn just x into a String you could do this:

String txt=""+x;

Also, there is a class associated with primitive types which provides toString methods:

String txt=Integer.toString(x);

For Integer there are also variations to generate String representations in different bases.
