In Java how can I access a variable from outside the anonymous class [duplicate]

Question

This question already has answers here:

How can I pass a non final variable to an anonymous inner class? (2 answers)

Closed 8 years ago.

for example:

for (int i = 0; i < 10; i++){
   SomeClass something = new SomeClass();
   something.setOnClickListener(new OnClickListener() {
      public void onClick(){
         doSomething(i);
      }
   });
}

I am not allowed to use the variable i, Eclipse suggest me make the i final, but I cannot do that because I need it to iterate right?

Answer 1

Copy i to a final variable in the loop body.

for (int i = 0; i < 10; i++){
   final int j = i;
   SomeClass something = new SomeClass();
   something.setOnClickListener(new OnClickListener() {
      public void onClick(){
         doSomething(j);
      }
   });
}

Answer 2

You can do

loop with i
  final int k = i
  annonymousClass
