# What is final variable in java?

If you make any variable as final, you cannot change the value of final variable(It will be constant).\
There is a final variable speedlimit, we are going to change the value of this variable, but It can't be changed because final variable once assigned a value can never be changed.\
\

```
class Bike9{   final int speedlimit=90;//final variable   void run(){    speedlimit=400;   }   public static void main(String args[]){   Bike9 obj=new  Bike9();   obj.run();   }  }//end of class  
```

\

**Output:**Compile Time Error
