Java HotSpot Virtual Machine

public static void myMethod( String Argument)
{
int i = 0 ;

.....

}

What are the chances of data corruption in this static method?

IF there are chances of data corruption, am I corrupt in saying that chances of data corruption for argument and Variable i are same?

Where is function state stored in static method stored? What will happen to this if one thread pre-empts other?

public class a
{
int j;
public static void myMethod( String Argument)
{
int i = 0 ;

.....

}
}


How is integer j different from integer i? Where will JVM keep these variables ?
