Why is there that much machine code compiled from my Java source code?

I compiled the following source code in Introductions.java:

import java.io.*;
public class Introductions {
    public static void main( String[] args ) {
        Console console = System.console();
            console.printf("hello");
    }
}

/*

public class name as file name (case sensitive).

*/

I got, in Introductions.class:

ֺ‏÷¾   4 
  
    
    <init> ()V Code LineNumberTable main ([Ljava/lang/String;)V 
SourceFile Introductions.java      hello java/lang/Object    
Introductions java/lang/System console ()Ljava/io/Console; java/io/Console printf 8(Ljava/lang/String;[Ljava/lang/Object;)Ljava/io/Console; !                     *· ±    
                 0     ¸ L+½  W±

Why is there that much machine code compiled from my Java source code? I mean, it seems much more than what I originally wrote.

Moreover, why is there English mixed with that machine code?

Hello, I don't think it is machine code. Java compiled code should be bytecode - https://www.beyondjava.net/blog/java-programmers-guide-java-byte-code/

Probably it is from the workspace and it can't display the format. I am not java expert, just consideration.
