Question

how to print this statement in java print r-x-1 2 x 1 logic used in python its perfect but java wrong output came

Answer 1

In ' '*(r-x-1) and '*'*(2*x+1), you used multiplication of strings, which python supports but java does not. The problem can be solved by writing a loop which adds to the string on every iteration.

String r=""; //creating a String variable to store the string to be printed

for (int i=1; i<=(r-x-1); ++i) { //loop will repeat (r-x-1) times

    r=r+" "; //adding ' ' to r every time the loop runs

}

for (int i=1; i<=(2*x+1) { //loop will run (2*x+1) times

    r=r+"*"; //adding '*' to r every time the loop runs

}

System.out.println(r); //printing r

Hope this helps. :) Lemme know if this solved your problem, k?
