构造函数中生成的数组怎么在内部类使用？

[Craftsman98]

public class Line1 extends JFrame{
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	
	
	
	public Line1(String[] array, String title) {
		String[] station;
		station = array;
		JButton[] stationButton1 = new JButton[station.length];
		
		Container container = getContentPane();
		setLayout(new GridLayout(6, 5,10,10));
		for (int i = 0; i < station.length; i++ ) {
			stationButton1[i] = new JButton(station[i]);
			container.add(stationButton1[i]);
		}
		setSize(800, 600);
		setTitle(title);
		setDefaultCloseOperation(DISPOSE_ON_CLOSE);
	}
	
	
	
	
	public class stationSelect implements ActionListener{

		@Override
		public void actionPerformed(ActionEvent e) {
			// TODO Auto-generated method stub
			int index = new PrintArray(stationButton1, e).getIndex();  //这里stationButton1会报错
			
			
		}
		
	}

}

怎样让stationButton1数组能够在内部类中使用？小菜鸟刚刚学习java，请各位大佬指导

定义提到外面

变量定义的范围问题，如果变量是几个内部类中都要使用的，整个类中定义而不是单独在某个类中定义
