e692. associating a label with a component.txt

这里面包含了一百多个JAVA源文件

When a label is associated with a component, you should call setLabelFor() to make the association explicit and then set a mnemonic on the label. The associated component will get the focus when the mnemonic is activated. 
    JLabel label = new JLabel("Name:");
    label.setDisplayedMnemonic('N');
    label.setLabelFor(component);
