import java.util.scanner;  public class myline {  public static void main(string[] args) {     string currentline = new string();     int length =0;       scanner sc = new scanner(system.in);         int x = sc.nextint();          if (currentline.charat(0) == 'l') {             return '*' x times;         }     }  } 

the last line me taking note of want do. if user puts in number x, how return * character many times?

you can't return in main (it's void method). aren't using length, , if understand question use stringbuilder , simple for loop. print contents of stringbuilder. like

public static void main(string[] args) {     scanner sc = new scanner(system.in);     int x = sc.nextint();     stringbuilder sb = new stringbuilder();     (int = 0; < x; i++) {         sb.append('*');     }     system.out.println(sb.tostring()); }
