Method Local Inner class

[Arjun Reddy]

Hi Guys,

I was wondering if we can access Local variables of an Outer Class's method that has an Inner class. I wrote the following code and I don't know how to do it.I can access the member varible of outer class tho from the inner class tho.

package com.gss.innerclasses.methodlocal;
 
public class OuterClass2 {
 
private int j=10;

void display()
{
[B]int i=10; //Local variable how to access this?[/B]

class InnerClass2
{
void display2()
{
System.out.println(OuterClass2.this.j); //accessing the outer class member variable from Inner class
}


}
InnerClass2 InnerObject = new InnerClass2();
InnerObject.display2();





}

public static void main(String args[])
{
OuterClass2 OuterObject = new OuterClass2();
OuterObject.display();
}


}

Thanks.

If you make the local variables final, then you can access them from a method-local class.

For example, if i were final, then you could access it from InnerClass2.

Hi Marc,

Thanks for ya reply. Can you tell me how I'd be able to do that from the code I wrote?

Thanks.

Hi Rancher ,

In method local inner class , you can access only local final variables .
If you declare variable i as final , you can access it.

Hi Madhukar,

Can you tell me how to access the local variable tho after declaring it as final?

I was able to access the outer class instance variable using OuterClass.this.j but how do I access the local variable?

Thanks.

Hi Marc,

The post you closed was not a duplicate of this one. This post is regarding Method Local Inner Class and that was regarding Anonymous Inner Class. I did not want to post both of em in the same post as there might be some confusion.

Thanks.

Hi. Below is from geekevaluation.com, regarding method local inner class. I know that final variables of methods can only be accessed by its method local inner class. Then why not in below mentioned code?

public class etattva101 {
    
    public static void main(String[] args) {
            final int a;    // Line 1
            final int b;    // Line 2
            b=10;           // Line 3
            class MethodLocalClass {
                    a=19;  //Line 4   
                   
            }
            
    }
}

Here a is final variable only. Still at Line 4, there is a compiler error. Somebody please give me a proper explanation for this. Thanks.
