Final static string vs Static string in java

Static final variable java example:

• If we declare any variable as static means it is class level variable.
• If we declare any variable as static final its class level variable and its value can not be changed 
• final static variables are constants in java.
• We can access these final static variables directly without using object or class name.
• We can not change the value of final static variables in any object.

java example program on final static variable

7. System.out.println(str); 
8.  //str="j2ee Interview Questions"; gives error
9. 
   
10. }
11. }
