Array returning memory allocation instead of value in Java -

this question has answer here:

• how print java object without getting “sometype@2f92e0f4”? 8 answers

consider simple case 1 :

public static void array() {     string mystring = "stackoverflow";     int [] checkval = new int[mystring.length()];      for(int i=0; i<mystring.length();i++){         checkval[i] = (int)mystring.charat(i);     }      system.out.println(checkval[0]);     system.out.println(checkval[1]);     system.out.println(checkval[2]);     system.out.println(checkval[3]);     system.out.println(checkval[4]);     system.out.println(checkval); } 

this output following :

83 84 65 67 75 [i@fc9944 

can 1 please explain me ? how can retrieve proper information array instead of it's memory allocation ?

if want pretty printed, use arrays.tostring it:

system.out.println(arrays.tostring(checkval); 

if not, print out tostring of array, inherited object, , generated string contains type , hash code:

the tostring method class object returns string consisting of name of class of object instance, at-sign character `@', , unsigned hexadecimal representation of hash code of object. in other words, method returns string equal value of:

getclass().getname() + '@' + integer.tohexstring(hashcode())
