How do I pass local final variable value to global variable.

Question

Hi,
In my code, I need to pass the local final string varibale value to the global variable for further usage. I know final is constant and inside the braces it can't be modified or assigned to other. Help needed in this regard or how do I re-modify the code according to my requirement i.e assigning the final string variable value to the outside of that block.I need the value of final String variable to be available in the process method outside of the specified block.
class HostConnection{
public module process(){
     HostKeyVerification hkv = new HostKeyVerification() {
          public boolean verifyHost(String hostname,SshPublicKey key) {
final String keyfingerprint = key.getFingerprint();               return true;
Thanks

It seems to be by-default all varibales in the inner calss method are Final.This is not true. Try this:
class SomeClass {
  public void method() {
    Runnable runnable = new Runnable() {
       public void run() {
          int i = 0;  // new inner-class variable
          i = i + 1;
          System.out.println(i);  //prints "1"
}But you obviously can't do this:
class SomeClass {
  public void method() {
    Runnable runnable = new Runnable() {
       public void run() {
          int i = 0;  // new inner-class variable
          i = i + 1;
          System.out.println(i);  //prints "1"
    System.out.println(i); //compiler error: "i" is undefined
}Because you are declaring i in an inner class. If you want to access the value of i outside that inner class, you'd have to do this:
class SomeClass {
  private int i;
  public void method() {
    Runnable runnable = new Runnable() {
       public void run() {
          int i = 0;  // new inner-class variable
          i = i + 1;
          System.out.println(i);  //prints "1"
          SomeClass.this.i = i;
    System.out.println(i); //no compiler error
}If this doesn't answer your question, please try to post an actual question, along with your real code, and any compiler errors you are getting, word for word.
