string to char array, showing silly characters

Question

It is a really simple question but I need an another eye to look at my code:

String strtr = \"iNo:\";
char[] queryNo = strtr.toCharArray();
System.out.println(qu         


        

Answer 1

That's how toString() is implemented for arrays.

The [C denotes that is a char array, 177b4d3 is its hashcode.

You may want to look at

System.out.println(Arrays.toString(queryNo) + " =this is no");

if you want to see your original String again, you need this:

System.out.println((new String(queryNo)) + " =this is no");
