Why is it illegal to use an access modifier when creating a new object? Like this:
public GoKart newGoKart = new GoKart("red");
instead of:
GoKart newGoKart = new GoKart("red");

As Michael McDonald commented,</p><p> It is illegal to use access modifiers on any variable inside a method.</p><p> Access modifiers may be used to specify access of class variables such as data members and methods/functions.</p><p> Similarly, it can be used when creating objects too, as can be seen from the sample code below, but not within methods/functions.</p>
A.java
public class A
{
private String mStr="";
A(String str)
{
mStr = str;
}
public String getString()
{
return mStr;
}
}
Introductions.java
import java.io.Console;
public class Introductions {
static public A a = new A("Hello");
public static void main(String[] args) {
System.console().printf("Hi\n");
// Welcome to the Introductions program! Your code goes below here
System.out.println(a.getString());
}
}
Console
treehouse:~/workspace$ javac A.java && javac Introductions.java && java Introductions

1,420 PointsA follow up question on the above solution:
Suppose String mstr was public, then there should be no need for the getString() method. Then in the introductions class, can we print the string in the a object by using the command line a.str instead of a.getString().
