when we combine char array with strings in pritln method why char array will converted into byte code in java? -

public class afgh {     public static void main(string[] args) {              string s2=new string("thisissurya");             char[] buf= new char[30];             s2.getchars(0,4,buf,0);             system.out.println(buf);             }      } 

it give output correctly : if change code when write

public class afgh {     public static void main(string[] args) {              string s2=new string("techfortelangana");             char[] buf= new char[30];             s2.getchars(0,4,buf,0);             system.out.println("the chars :"+buf);             }      } 

but giving output: chars :[c@138532dc why char array directly converted string?? when concatenating??!

that's not bytecode directly printing character array printing array reference string string representation of array.

use arrays.tostring(array) or iterate on array print array elements.

• [c c means character class [ means array
• @ @ rate character
• 138532dc hashcode of object converted hexadecimal string
