To set constraints using SpringLayout, you use the putConstraint() method of the layout manager.
The method takes several arguments:
putConstraint(int edge1, Component c1, int pad, int edge2, Component c2)
- edge1 and edge2 specify the edges to be aligned or anchored.
- c1 and c2 are the components to be aligned or anchored.
- pad is the padding (distance) between the edges.
In the example code above, constraints are set using putConstraint() to specify the position of the components.
