if-then-else-then-if implementation in java 8

I'm trying to implement if-else-if statement. I know there are some way like Optional with filters/ stream with filters for implementing if-else statement.

Can someone will help me out following pseudo code for if-else-if statement.

//i is loop count.
int size = 3;
if( i = size){
    System.out.println(i);
} else if(i < size){
    System.out.println(i);
} else if(i > size){
    System.out.println(i);
}
