When you change the words between the quotation marks, Java displays the text No more baked beans

With each of these changes, you get error messages. Java is case-sensitive. In this example, the correct words are public , main, and System.

With the missing semicolon, you see a red error marker in your IDE's editor. Java can't compile this code.
In many cases, with extra semicolons, the code runs correctly. The additional semicolon is considered to end an empty statement (a statement with no code).

With the indentation and line breaks changed, the code runs correctly. Java doesn't care about indentation or line breaks unless it's in the middle of a quoted string of characters.
When you change println to print1n, you get an error message. Java doesn't know what print1n means.
Java displays the text Use a straight quote ", not a curly quote ” which ends with a curly quotation mark. In Java, \" represents a straight quotation mark to be displayed on the screen, and \u201D represents a curly quotation mark to be displayed on the screen.
