Method calls inside a Java class

Question

I was setting out to write a piece of code today in Eclipse, and I started out like so:

public class MyClass {
    System.currentTimeMillis();
}
         


        

Answer 1

You dont get the error with the line

long time = System.currentTimeMillis();

because you are specifying a private variable inside the class (long time) and setting them to a default value (System.currentTimeMillis()) so when you make a new instance of the class MyClass, the variable is being instantiated.

calling only System.currentTimeMillis() just has nosense, because you arent doing nothin' (neither having a context or assigning the value to a private variable)
