for loop with multiple variables

[kevinn lee]

 
class Forr{
	public static void main(String[] args){
	

		int i=0;
		for ( i=0,int j=90; i<j; i++) { j--; }
	}
}   

why doesent compiler allow to use a pre declared variable and a variable declared within the for loop together?
code compiles when both are declared within and when both are declared out of the loop.
or is it because line "i=0,int j=90;"it self is faulty when taken alone?

thanks

i=0,int j=90 is not a valid java statement, so it is not allowed.

You can try the following:-

 class TestFor {
  public static void main(String[] args){
   
    int i=0;
    for(int j=90;i<j;i++) {
      // You can use both i and j here.
    }
  }
}
