Eclipse uses 4 spaces instead of tab

As mentioned in the Java Code Specification, tab is actually 8 characters, so we can use 4 spaces (4 characters) instead of tab, which reduces the storage size of the code and provides an aesthetically pleasing code.

So modifying the encoding format of Eclipse helps us to replace it without changing our habits.

The steps are as follows:

2. When editing, the tab is replaced. Text Editors, Editors, General, Windows-Preferences, select the Insert spaces for tabs.

4. Replace the tab with CTRL + Shift + F when formatting the code. Preferences, Java, Code style, Formmater, Windows----Active profile Select a formatting style, and then click Edit. In the Indentation tab, locate the general settings and select Spaces only in the tab policy.
