The standalone editor comes with its own main window and menu bar. All important menu items are bound to astandard keyboard shortcut. The keyboard shortcut is displayed in the respective menu item. You can use the"File / Open File..." (CTRL-O) menu item to open a file or drag the file you want to open and drop it insidethe editor area. To start editing a new file from scratch using the "File / New" (CTRL-N) menu item.

You can insert other files by copying them to the clipboard. This can be achieved for example via "Edit /Copy" (CTRL-C) in Windows and pasting it in javahexeditor via "Edit / Paste" (CTRL-V). Copying to atext editor has a limit of 4 MB. Binary copying (from javahexeditor to javahexeditor ) islimited by the free disk space only.
A Source-Code Editor (or Programming Text Editor) is programming language sensitive and context-aware. It highlights the syntax elements of your programs; and provides many features that aid in your program development (such as auto-complete, compile/build/run, help menu, etc.). On the other hand, a plain text editor, such as Windows' NotePad and macOS's TextEdit, is not language-sensitive and, therefore, is NOT suitable for writing programs.
There are tons of "free" program editors available. Google "best source code editor" to find out the latest. Here are some program editors that I am currently using. Unfortunately, there isn't one magic wane (or silver bullet) that suits all my programming needs.
TextPad is a light-weight source-code editor, especially good for writing toy Java programs. It is simple to use, fast to launch, and it can be configured to run JDK commands directly. TextPad is a shareware (not a freeware). It has no time limit but a message will keep reminding you to purchase the shareware.
Pre-installed in Windows 10, Code Writer is a free text and code editor app with over 20 supported file types, and active syntax highlighting that updates as you edit documents. Use it as a replacement for Notepad and other quick edit apps.
PSPad is an excellent program editor, especially for web programming such as writing JavaScript. It is a freeware. To install, simply run the downloaded installer. The "Help" menu provides many good links to various online programming guides and references.
Some systems, such as Ubuntu Server, do not support graphical user interface. Hence, it is important to be able to use a text-based editor, such as nano and vim, to do minor editing (such as changing the configurations).
A spinner is a compound component with three subcomponents: two small buttons and an editor. The editor can be any JComponent, but by default it is implemented as a panel that contains a formatted text field. The spinner's possible and current values are managed by its model.
The code for the main class can be found in SpinnerDemo.java. The Month spinner displays the name of the first month in the user's locale. The possible values for this spinner are specified using an array of strings. The Year spinner displays one value of a range of integers, initialized to the current year. The Another Date spinner displays one value in a range of Date objects (initially the current date) in a custom format that shows just a month and year.
When you set the spinner's model, the spinner's editor is automatically set. The Swing API provides an editor class corresponding to each of the three model classes listed above. These classes — JSpinner.ListEditor, JSpinner.NumberEditor, and JSpinner.DateEditor — are all subclasses of the JSpinner.DefaultEditor class that feature editable formatted text fields. If you use a model that does not have an editor associated with it, the editor is by default a JSpinner.DefaultEditor instance with a non-editable formatted text field.
The JSpinner.NumberEditor and JSpinner.DateEditor classes have constructors that allow you to create an editor that formats its data in a particular way. For example, the following code sets up the Another Date spinner so that instead of using the default date format, which is long and includes the time, it shows just a month and year in a compact way.
To change the formatting when using a default editor, you can obtain the editor's formatted text field and invoke methods on it. You can call those methods using the getTextField method defined in the JSpinner.DefaultEditor class. Note that the Swing-provided editors are not formatted text fields. Instead, they are the JPanel instances that contain a formatted text field. Here is an example of getting and invoking methods on the editor's formatted text field:
As we mentioned before, if you implement a spinner model that does not descend from SpinnerListModel, SpinnerNumberModel, or SpinnerDateModel, then the spinner's default editor is a non-editable instance of JSpinner.DefaultEditor. As you have already seen, you can set a spinner's editor by invoking the setEditor method on the spinner after the spinner's model property has been set. An alternative to using setEditor is to create a subclass of the JSpinner class and override its createEditor method so that it returns a particular kind of editor whenever the spinner model is of a certain type.
In theory at least, you can use any JComponent instance as an editor. Possibilities include using a subclass of a standard component such as JLabel, or a component you have implemented from scratch, or a subclass of JSpinner.DefaultEditor. The only requirements are that the editor must be updated to reflect changes in the spinner's value, and it must have a reasonable preferred size. The editor should generally also set its tool tip text to whatever tool tip text has been specified for the spinner. An example of implementing an editor is provided in the next section.
The following tables list some of the commonly used API for using spinners. If you need to deal directly with the editor's formatted text field, you should also see The FormattedTextField API. Other methods you might use are listed in the API tables in The JComponent Class.
Without going into too much detail here, the most important part is replacing the IDocumentProvider of the editor. This converts binary data both when reading text and writing back to binary format. In a future article I'll go into more detail about the technique, but today will just stick to the use and functionality of the Java bytecode editor.
Why might you be interested in the contents of .class files and using an editor on them? In most projects the Java code itself is interesting, but not what the compiler makes of it. But there are cases in which a viewer and possibly an editor for the binary data could be helpful.
To open the .class file associated with a .java file, an Open JBC entry is provided in the Package and Project Explorer context menu. Executing this opens a new editor that displays the bytecode as a DSL.
The editor displays each byte as a hexadecimal number. The only exception is UTF8 strings, which are represented as they are in Java; this is to provide enhanced editability. Changing a string value is as easy as it is in Java code. The data is enriched with keywords and grouping brackets to highlight its meaning. The presentation corresponds directly to what you can get from the Java Spec via the ClassFile format.
In the bytecode the length of a table is display before each table. This length must be adjusted if entries are deleted or added using the editor. The editor therefore offers validation that compares the actual lengths of tables with their specified lengths. If they do not match they are highlighted as errors and can be adjusted via Quick Fix (Ctrl + 1).
Information displayed by hovering, together with the outline, can provide further understanding of the bytecode. The elements from the editor are also shown here, but with resolved references and interpreted values. For example, any access modifiers of a class are displayed textually rather than as a hexadecimal number, as in the editor.
If you will try to open .class file directly in any text editor, it doesn't open in readable format. You need to have editor which supports opening file in Hex format. You can use notepad++ for that purpose. However, you need to install HEX-Editor plugin. Here are the steps for the same :
Try either cd "PATHTOFOLDER" or shift + right click and press "open command window here" before typing in java -jar LR2_hexEdit.jar. That's what I have to do, because I can't figure out how to get the first C:[path-to-folder] to work in the command.

JOE is a blending of MicroPro's venerable microcomputer word processor WordStar and Richard Stallman's famous LISP based text editor GNU-EMACS (but it does not use code from either program): most of the basic editing keys are the same as in WordStar as is the overall feel of the editor. JOE also has some of the key bindings and many of the powerful features of EMACS.
Much of the look and feel of JOE is determined by its simple configuration file "joerc". Several variants of the editor are installed by default in addition to "joe": "jmacs" (emulate GNU-EMACS), "jstar" emulate WordStar, "jpico" emulate the Pine mailer editor PICO and "rjoe"- a restricted version of JOE which allows the used to only edit the file given on the command line. JOE is linked to several names. The name which is used to invoke the editor with "rc" tacked on the end gives the name of configuration file to use. It is thus easy for you to make your own variant if you want. Also you can customize the editor by copying the system "joerc" file to your home directory. 2ff7e9595c
