Java Array Output Confusing

Taken from this site: https://www.journaldev.com/770/string-byte-array-java

package com.journaldev.util;

public class ByteArrayToString {

    public static void main(String[] args) {
        byte[] byteArray = { 'P', 'A', 'N', 'K', 'A', 'J' };
        byte[] byteArray1 = { 80, 65, 78, 75, 65, 74 };

        String str = new String(byteArray);
        String str1 = new String(byteArray1);

        System.out.println(str);
        System.out.println(str1);
    }
}

Why is the output:

PANKAJ

PANKAJ

I can't see how it isn't:

Try this code:

public class ByteArrayToString {
  public static void main(String[] args) {
        byte[] byteArray = { 'P', 'A', 'N', 'K', 'A', 'J' };
        byte[] byteArray1 = { 80, 65, 78, 75, 65, 74 };

        String str = new String(byteArray);
        String str1 = new String(byteArray1);

        System.out.println(str);
        for (byte b : byteArray1) {
            System.out.print(b);
        }
        //System.out.println(str1);
    }

} Program output

byte[] bytes constructor will parse the data contained, as @khelwood said it comments, the number are the ASCII representation of the letter so 80 represents a 'p' character.

if you want your output as you want, you should use

String[] srtArray = {"P","A"...}
String[] srtArray = {"80","65"...}

In the case of { 'P', 'A'...}, they are already encoded but number will be converted since they are stated as numbers and not string. "80" is not the same as 80.
