Accessing Members in Enclosing context

Question

hi all.. I am new to java. I came across this example that didnt make sense to me and wondering if someone can explain it to me. It is about nested classes, specificly static member classes.
In the code below under the method public void nonStaticMethod_1_1_1().
the assignment statment int kk = k is allowed how come?
// Filename: AccessInTopLevelClass.java
public class AccessInTopLevelClass {                            // (1)
public void nonStaticMethod_1() {                           // (2)
System.out.println("nonstaticMethod_1 in AccessInTopLevelClass");
private static class StaticMemberClass_1 {                  // (3)
private static int i; // (4)
private int j; // (5)
public static void staticMethod_1_1() {                 // (6)
System.out.println("staticMethod_1_1 in StaticMemberClass_1");
interface StaticMemberInterface_1_1 { int Y2K = 2000; } // (7)
protected static class StaticMemberClass_1_1
implements StaticMemberInterface_1_1 {          // (8)
private int k = Y2K; // (9)
public void nonStaticMethod_1_1_1() {               // (10)
// int jj = j; // (11) Not OK.
int ii = i; // (12)
int kk = k; // (13)
// nonStaticMethod_1(); // (14) Not OK.
staticMethod_1_1(); // (15)
public static void main (String[] args) {
int ii = i; // (16)
// int kk = k; // (17) Not OK.
staticMethod_1_1(); // (18)
}

try to use code tag. it's easier for other to read.
interface StaticMemberInterface_1_1 {
               int Y2K = 2000;
          } // (7)
          protected static class StaticMemberClass_1_1 implements
                    StaticMemberInterface_1_1 { // (8)
               private int k = Y2K; // (9)
               public void nonStaticMethod_1_1_1() { // (10)
               // int jj = j; // (11) Not OK.
                    int ii = i; // (12)
                    int kk = k; // (13)
                    // nonStaticMethod_1(); // (14) Not OK.
                    staticMethod_1_1(); // (15)
               public static void main(String[] args) {
                    int ii = i; // (16)
                    // int kk = k; // (17) Not OK.
                    staticMethod_1_1(); // (18)
the assignment statment int kk = k is allowed how come?whats the prob? kk is a local variable. and k is member of StaticMemberClass_1_1 that is not static.
since k is not static member, u only accessing k in an instance of class. in your main method which is static, u can't accessing k.
