Question

which variable is used the assign the initial and final value

Answer 1

In Java, non-static final variables can be assigned a value either in constructor or with the declaration. But, static final variables cannot be assigned value in constructor; they must be assigned a value with their declaration.

For example, following program works fine.

class Test {

  final int i;  // i could be assigned a value here also

  Tets() {

    i = 10;

  }

 

  //other stuff in the class

}



If we make i as static final then we must assign value to i with the delcaration.

class Test {

  static final int i = 10;  // Since i is static final, it must be assigned value here only.

 

  //other stuff in the class

}
