e853. laying out components in a grid.txt

这里面包含了一百多个JAVA源文件

When components are added to the container, they fill the grid left-to-right, top-to-bottom. 
    int rows = 2;
    int cols = 2;
    JPanel panel = new JPanel(new GridLayout(rows, cols));
    panel.add(component1);
    panel.add(component2);
