     Argument: Your should choose File Name Without Extension

Now you can find these two tools with Menu text name in Tools menu with short cuts

Compiler: Ctrl+1 & Ctrl+2 as shown below

Rule in developing java file from Editplus:

To execute java program from editplus, the Java file name must be same as class name even though class is not public. Else you will get exception "java.lang.NoClassDefFoudError"

Why this rule?

Recollect the configuration done for java tool.

We set Argument value as "FileName without extension".

For Example 

If we create class with name A and java file name with name Example.java.

EditPlus Software 

Compiles this java file as

  javac Example.java

Executes the class as

java Example

So in this case JVM throws " java.lang NoClassDefFoundError: Example" as there is no Example.class, instead we have A.class.

Note:

This rule is common for all editor softwares those support in-build compilation and execution.

How does it display compilation, execution errors and output?

For compilation and execution it also uses command prompt. So all compilation, execution errors and output is displayed on command prompt windows as shown below.

To enable Line number

Open java editor -> Click on View -> Line Number menu item.

Short-cut: Ctrl+shift+L

How Can it display keywords, predefined classes in blue and red colors:

All predefined class names are saved in file, that file path is

C:\Program Files\EditPlus 3\java.stx

In Editplus, this file path is configured in the below window

Click on Tools -> Preferences menu item ->

Click on Files -> Settings & syntax

Click on Syntax colours tab,you will be shown default configured colours.

Short-cut for copy & past existed single line:

Place cursor anywhere on the line that you want to copy & paste , and then press Ctrl+J.
