square of character inside square of another character in java -

i want print square of character in format basad on the number of lines example :

    number of lines : 4      output :                 b   b        b   b               number of lines : 5      output :           a        b   b  b       b   c  b       b   b  b          a 

but didn't know how result , code

import java.util.scanner; public class test {      public static void main ( string arugs [] ) {          scanner read= new scanner(system.in) ;         system.out.println ( " please inter number of line : " ) ;          int size = read.nextint();         int []array = new int[size ];          int c = 97;          for(int = 0; < size; ++i) {              for(int j = 0; j < size; ++j){                 array[i]= c;                 system.out.print( (char)array [i]);}                  system.out.println();              }         }     } } 

a funny way :

public static void main(string arugs[]) {     scanner sc = new scanner(system.in);     system.out.println("please enter number of lines : ");     int size = sc.nextint();     sc.close();      (int = 0; < size; i++) {           (int j = 0; j < size; j++) {               system.out.print((char) ('a' + math.min(size - j - 1, math.min(size - - 1, math.min(i, j)))) + " ");           }           system.out.println();       }   } 

the idea :

• we need calculate "depth" of particular point (i, j). value of cell 'a' + depth
• the depth defined minimum distance of point edge of matrix
