Why I obtain this error although I declared the type of I as int in the for loop?

Question

Import java.util.*;
Public class prog{
public static void main (String[] args){
int sum=0;
for(int i=0;i<3;i++);
sum+=i;
System.out.println(sum);
}
}

Answer 1

because of the semicolon after for loop

Answer 2

Thanks Friends for your help 😊

Answer 3

Hichem GOUIA , I think your problem is that you put semicolon in the line of the loop. Loop has to be enclosed in curly brackets.

Answer 4

No it's not because of the semicolon.
If I add a new line int i=0; After the int sum=0; the code compiles
I have a doubt here if the i is considered as a local variable for the for loop...
