Question

Whenever I try to print the char arrays to the console, I’m getting the result in integer format, but whenever I try to print integer arrays to the console, I’m getting the result in hashcode format. Could anyone please tell me why?

char[] arr={'4','5','6'};
System.out.println(arr); //456

int[] arr={4,5,6};
System.out.println(arr) //[I@3e25a5]

Answer 1

java.io.PrintStream (the class of System.out) has a special print-method for char[], but not for int[]. So for the char[], this special method is used, while int[] is printed via the generic version, which prints the hashcode (or, to be more precise, the result of String.valueOf() called with the object as parameter).
