What are some common functions of eclipse ??

Many people have said that after using eclipse, they have abandoned other java ides, indicating that it must be nice.
Let me introduce how to develop java using eclipse.

[Java Development Tool (JDT) features]

In fact, there are many features. Based on my development experience, I will introduce the outstanding features of jdt.

1. Automatically modifycode
To a large extent, this function automates the trivial work in some development code at ordinary times.

Open menu
+ Source
-Comment: This is useful. For example, if you write java code and find that you have a piece of code to note
Release the code, select the code, and then select the code. Then, the code will be automatically commented out.

Jian is "Ctrl + /"

-Uncomment: Uncomment. the operation method is similar to that of Comment. The shortcut key is "Ctrl + \"

-Format: I have always recommended this operation item, which is very convenient. For example, if you write a cell
Bad code, messy, then you choose this one, you will find, wow ~~, My code

You can try it if you don't believe it. The shortcut key is "Ctrl + Shift + F", so now I have started to learn
I am used to writing code for a while, just like c + s + f. It's very convenient.

-Sort Member: This is not very common, but if you think the code is too long, you can't find a letter.
Number, you can also try it. It will help you sort the functions and variables you have written.

-Organize Import: this function is not uncomfortable. For example, if you compile a project,
It is found that many imports are not used, or you reference a class, but you do not have import,

It doesn't matter if the result is not compiled. Once this is used, all the problems can be solved. At least after I use this
I have never written such statements as import. The shortcut key is "Ctrl + Shift + O (it is the letter O, not the number

0) ", I often use this with c + s + f.

-Override/Implement Method: for example, if you write a class to Implement an interface
If you have not implemented the function of that interface, use this function to automatically search for the parent class and Interface

Method, you can choose whether to overwrite or implement which functions

-Generate Getter and Setter: if you add a class variable, write getter and se for it.
Tter, it doesn't need to be so troublesome. It's all automatic.

-Generate Delegating Method: If a field needs to Generate a proxy function,
Click OK.

-Add Javadoc Comment: Specifies a function, class, or variable that you want to Add javadoc.
Select this option. It will automatically add the javadoc header, including the param or return

-Surround with try/catch block: for example, if you have a piece of code to handle some exceptions,
But you forgot to use try/catch to write it again. Don't worry. Select the code and select this one. You will find that it will

Automatically tests the exceptions in your code and generates all the code.

-Externalize string: This is used for internationalization. Simply put, the string
Package is in resource bundle, which is also a solution of i18n.

Introduce this.

2. refactoring:
Refactoring has been very popular over the past two years. Let's see how strong the Refactoring is in jdt.
