把这段话翻译成中文：Initially, Jordan mentioned that the Pre-Configuration feature was not working, even with both EX920 meshed and connected to the internet. When the testing started I deleted the network and factory reset the devices then powered them off. I created the network in the portal and enabled pre configuration parameters. Powered on the main unit and after a short time the network came online in the portal, we powered on the satellite unit and also came online in the portal. These initial testing show the appropriate behavior. later on, Jordan attempted to recreate the previous test and mentioned it did not work for him, the network remained inactive in the portal. On our next troubleshooting call I followed the exact same previous steps and the network remained inactive in the portal.

首先，乔丹提到，即使EX920互联网拓扑结构连接在网络上，预配置功能也无法正常工作。在测试开始时，我删除了网络，并对设备进行了恢复出厂设置，然后将其关闭。我在门户中创建了网络，并启用了预配置参数。打开主机，短时间内网络就在门户中上线了，我们打开卫星单元，也在门户中上线。这些初始测试表明了适当的行为。后来，乔丹试图重新创建之前的测试，但他说它对他来说不起作用，网络仍然在门户中处于不活动状态。在我们的下一次故障排除电话中，我按照完全相同的步骤，网络仍然在门户中处于不活动状态。

use Java to achieve that:Write a program to display font sizes Layout It should have: ● In the top: - label for letter “X” - label for font size value ● In the bottom: - button to increase font size - button to decrease font size Desired final look: Functionality Initially, the X label should display an 18 point “X”, and the font size label should display the value “18”. Every time the “increase” button is selected, the font size of the “X” and the value in the font size label should be increased by 1. Every time the “decrease” button is selected, the font size of the “X” and the value in the font size label should be decreased by 1. Make sure that this does not allow negative font sizes.

Sure, here is the Java code to achieve the same functionality:

import java.awt.Font;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class FontSizer extends JFrame {
    private JLabel xLabel;
    private JLabel fontSizeLabel;
    private JButton increaseButton;
    private JButton decreaseButton;
    private int fontSize;

    public FontSizer() {
        super("Font Sizer");
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.setSize(300, 200);

        // create top panel with "X" label and font size label
        JPanel topPanel = new JPanel();
        this.xLabel = new JLabel("X");
        this.fontSize = 18;
        this.fontSizeLabel = new JLabel(Integer.toString(this.fontSize));
        this.fontSizeLabel.setFont(new Font("Helvetica", Font.PLAIN, 14));
        topPanel.add(this.xLabel);
        topPanel.add(this.fontSizeLabel);

        // create bottom panel with increase and decrease buttons
        JPanel bottomPanel = new JPanel();
        this.increaseButton = new JButton("Increase Font Size");
        this.increaseButton.addActionListener(e -> increaseFontSize());
        this.decreaseButton = new JButton("Decrease Font Size");
        this.decreaseButton.addActionListener(e -> decreaseFontSize());
        bottomPanel.add(this.increaseButton);
        bottomPanel.add(this.decreaseButton);

        // add panels to main frame
        this.add(topPanel);
        this.add(bottomPanel, "South");

        this.setVisible(true);
    }

    private void increaseFontSize() {
        this.fontSize++;
        updateFontSize();
    }

    private void decreaseFontSize() {
        if (this.fontSize > 1) {
            this.fontSize--;
            updateFontSize();
        }
    }

    private void updateFontSize() {
        this.xLabel.setFont(new Font("Helvetica", Font.PLAIN, this.fontSize));
        this.fontSizeLabel.setText(Integer.toString(this.fontSize));
    }

    public static void main(String[] args) {
        new FontSizer();
    }
}

This Java program creates a window with a label for the letter "X" and a label for the font size value. It also has two buttons at the bottom to increase or decrease the font size. The font size of the "X" label and the font size value label are updated whenever the user clicks on the increase or decrease buttons.

To use this program, save the code in a file with a ".java" extension and compile it using a Java compiler. Then, run the program using the Java Virtual Machine (JVM).

Write a program to display font sizes Layout It should have: ● In the top: - label for letter “X” - label for font size value ● In the bottom: - button to increase font size - button to decrease font size Desired final look: Functionality Initially, the X label should display an 18 point “X”, and the font size label should display the value “18”. Every time the “increase” button is selected, the font size of the “X” and the value in the font size label should be increased by 1. Every time the “decrease” button is selected, the font size of the “X” and the value in the font size label should be decreased by 1. Make sure that this does not allow negative font sizes.

Here is an example program written in Java using Swing library to display font sizes:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class FontSizeDisplay extends JFrame {

    private JLabel xLabel;
    private JLabel fontSizeLabel;
    private int fontSize = 18;

    public FontSizeDisplay() {
        setTitle("Font Size Display");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(300, 200);
        setLocationRelativeTo(null);
        setLayout(new BorderLayout());

        // Top panel with X label and font size label
        JPanel topPanel = new JPanel(new GridLayout(2, 1));
        xLabel = new JLabel("X", SwingConstants.CENTER);
        xLabel.setFont(new Font("Arial", Font.PLAIN, fontSize));
        fontSizeLabel = new JLabel(Integer.toString(fontSize), SwingConstants.CENTER);
        topPanel.add(xLabel);
        topPanel.add(fontSizeLabel);
        add(topPanel, BorderLayout.CENTER);

        // Bottom panel with increase and decrease buttons
        JPanel bottomPanel = new JPanel(new GridLayout(1, 2));
        JButton increaseButton = new JButton("Increase");
        increaseButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                fontSize++;
                if (fontSize > 0) {
                    xLabel.setFont(new Font("Arial", Font.PLAIN, fontSize));
                    fontSizeLabel.setText(Integer.toString(fontSize));
                } else {
                    fontSize--;
                }
            }
        });
        JButton decreaseButton = new JButton("Decrease");
        decreaseButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                fontSize--;
                if (fontSize > 0) {
                    xLabel.setFont(new Font("Arial", Font.PLAIN, fontSize));
                    fontSizeLabel.setText(Integer.toString(fontSize));
                } else {
                    fontSize++;
                }
            }
        });
        bottomPanel.add(increaseButton);
        bottomPanel.add(decreaseButton);
        add(bottomPanel, BorderLayout.SOUTH);
    }

    public static void main(String[] args) {
        FontSizeDisplay app = new FontSizeDisplay();
        app.setVisible(true);
    }
}

In this program, we create a JFrame window with a BorderLayout layout. In the center of the window, we create a top panel with X label and font size label, and a bottom panel with increase and decrease buttons. The X label is initially set to font size 18, and the font size label displays the value "18".

The increase and decrease buttons have action listeners that update the font size of the X label and the value in the font size label. We also make sure that the font size does not become negative.

When you run this program, you should see a window with an X label and a font size label in the center, and increase and decrease buttons at the bottom. Clicking the increase button will increase the font size of the X label and the value in the font size label by 1, and clicking the decrease button will decrease the font size by 1.
