How can add a line break inside the java's documentation

I have my constructor or any function/method which when I write this comment:

 /**
 * Comment Line 1.
 *  Comment Line 2.
 */

This no add a line break and show me all the text continue without line break.
This is a example

/**
* First line about the content of my class's constructor.
* Second line about the content...
* Third line about...
*/
public constructor(){

}

When I put the mouse pointer on the class show me the comment like this:

First Line about the content of my class’s constructor. Second line
about the content… Third line about…

Can anyone any idea about how add a line break?
