Java 在一个SWT应用程序中使用另一个SWT应用程序中的文本值（字符串）。（同一软件包）

我创建了两个SWT应用程序，我想从第二个程序（SWT应用程序）到第一个程序使用texteditor的值，因为它在同一个包中，应该可以使用，但它不是，有人能帮我吗

    public static void main(String[] args) {
        Display display = Display.getDefault();
        Shell shlNotepad = new Shell();
        shlNotepad.setSize(450, 300);
        shlNotepad.setText("Notepad");

        Menu menu = new Menu(shlNotepad, SWT.BAR);
        shlNotepad.setMenuBar(menu);

        MenuItem mntmFile_1 = new MenuItem(menu, SWT.CASCADE);
        mntmFile_1.setText("File");

        Menu menu_1 = new Menu(mntmFile_1);
        mntmFile_1.setMenu(menu_1);

        MenuItem mntmNew = new MenuItem(menu_1, SWT.NONE);
        mntmNew.addSelectionListener(new SelectionAdapter() {
            @Override
            public void widgetSelected(SelectionEvent e) {

            }
        });
        mntmNew.setText("New");

        MenuItem mntmSave = new MenuItem(menu_1, SWT.NONE);
        mntmSave.addSelectionListener(new SelectionAdapter() {
            @Override

            }
        });

            public void widgetSelected(SelectionEvent e) {
                FileEditor.main(args);
            }
        });
        mntmSaveAs.setText("Save As");

        MenuItem mntmExit = new MenuItem(menu_1, SWT.NONE);
        mntmExit.setText("Exit");

        texteditor = new Text(shlNotepad, SWT.BORDER);
        texteditor.setBounds(0, 0, 434, 241);
        String texted = texteditor.getText();


        shlNotepad.open();
        shlNotepad.layout();
        while (!shlNotepad.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }
    }
}

首先，你有两个主要的方法，所以有些地方已经不对劲了。除了在main中初始化一些东西之外，您不应该做任何事情，但肯定不要开始构建uit。这是两个不同的类耶，是一个程序。Java程序只有一个入口点。如果您运行两个应用程序，那么将有两个JVM在运行，并且它们之间没有通信。@Dici我知道，谢谢。
