Question

hi guys i am just doing some reading for myself to learn java and came across this problem and is currently stuck.

i need to print out series of number based on the input given by the user.
for example, if input = 5, the output should be as follows

@1@22@333@4444@55555

    import java.util.*;

public class ex5{
        public static void main(String[] args){
                Scanner kb = new Scanner(System.in);
                System.out.println("Please type a #: ");

                int input = kb.nextInt();

                for(int i=0;i<input;i++){
                        if(input==1){
                                System.out.print("@1");
                        }
                        if(input==2){
                                System.out.print("@1@22");
                        }
                }

        }
}

this doesnt seem to be working because this is the output i get

Please type a #:
2
@1@22@1@22

im not sure what to put inside the for loop right now and i dont think i am using the for loop here very well either…

any help guys?

Answer 1

    for (int i=1; i<=5; i++){
        System.out.print("@");
        for (int j=1; j<=i; j++) System.out.print(i);
    }

out

@1@22@333@4444@55555
