As you know, containers (such as JFrame, JPanel, ...) are used to hold controls in them, but they do not have or default to arrange objects that are not what we want. So we need to use java swing flowlayout to do this. In other words, Layouts allow us to arrange the controls in the containers in a logical and beautiful way.
Note that from now on the code may be long, so I only comment on the parts related to the subject of the article. With other parts not commented as mentioned in the previous posts, you can find yourself in the Blog by typing the keyword into the search box.
Java swing FlowLayout is a sort of object is arranged on one line, from left to right. We use Java swing FlowLayout when we want to sort objects consecutively on a line.

Create and set java swing FlowLayout for Container
The following example creates and sets the Java swing FlowLayout for JPanel that contains the JButton as shown:
File name: MyFlowLayout.java
Continue MyFlowLayout.java
Java swing FlowLayout initialization functions include:
- FlowLayout (): Initializes FlowLayout with objects that are centered by default, and the default vertical and horizontal spacing is 5 units.
- FlowLayout (int align): The same as above, but we specify the position of the alignment such as CENTER, LEFT, RIGHT, LEADING, TRAILING (LEADING, TRAILING and indicate the left alignment, must be relative according to the arrangement of Container).
- With this initialization we will set the margins and horizontal (hgap), vertical (vgap) between objects.
