It is correct Why?

[Poornima Sharma]

int []a={1,2,3,4,5,6,7,8,9};
for(final int b:a)
System.out.println(b);


Variable b is declared final but it is correct why?

[Vijitha Kumara]

Every iteration of the for loop will create a variable b which is marked final. Since you are not changing the variable b,no problem.

try

for(final int b:a){
b=0; //compiler ERROR
System.out.println(b);
}

Actually after compilation, the enhanced for loop becomes a general for loop. So you loop becomes something like this

int []a={1,2,3,4,5,6,7,8,9};
for(int i = 0; i< a.length;i++)
{
final int b = a[i];
System.out.println(b);
}
